CIRILLO, Judge:
Appellant, Kenneth King, appeals the order of the Court of Common Pleas of Philadelphia County declaring him to be the father of Christina Tyler, daughter of appellee, Marian Tyler. Appellant seeks a new trial or reversal of the finding of paternity. We find no error, and affirm.
*83Appellee filed a complaint for support for her daughter, born April 10, 1981. At the hearing, appellant was granted a continuance so that Human Leukocyte Antigen (HLA) blood tests could be taken of himself, appellee and the child, to determine the probability of his having fathered the child. Appellant stipulated that the test results were admissible as some evidence of paternity.
Appellee testified that she met appellant on July 25, 1980, and engaged in intercourse with him that night at his home. She also stated that on several occasions from April to July, 1980, she engaged in sex with another man. Appellant claimed that he did not meet appellee until October, 1980, and that she could not have spent the night of July 25 at his home because at that time his girlfriend and their daughter were living there. On cross-examination, appellee testified that she had lied to appellant about her use of a contraceptive, and that she had told a friend of appellant that another man may have fathered the child.
At the close of appellee’s case, appellant stated his belief that proper interpretation of HLA test results was a matter of statistics, and that these results lacked legal significance without expert testimony. However, he did not object to their admission into evidence. He then moved to dismiss, on the ground that the Commonwealth had not presented proper statistical evidence, in the form of expert testimony, to explain the test results. The motion was denied.
The court found appellant to be the father of appellee’s child. Following this determination, an order for support was entered.1
Appellant presents four questions: 1) Did the hearing court err in finding that appellant waived his right to cross-examine blood test examiners or a statistician to explain the test results? 2) Did the hearing court err in holding that appellant was not entitled to the benefit of Turek v. Hardy, 312 Pa.Super. 158, 458 A.2d 562 (1983)? 3) Did the hearing court deny appellant procedural due pro*84cess when it admitted the test results without allowing appellant the opportunity to confront and cross-examine appropriate experts? 4) Did the hearing court err by reaching factual conclusions contrary to the weight of the credible evidence?
We will dispose of appellant’s first and third questions together, as both concern his right to cross-examine witnesses.
Appellant relies on Section 6134 of the Uniform Act on Blood Tests to Determine Paternity,2 which states:
Selection of experts
The tests shall be made by experts qualified as examiners of blood types, who shall be appointed by the court. The experts shall be called by the court as witnesses to testify to their findings and shall be subject to cross-examination by the parties. Any party or person at whose suggestion the tests have been ordered may demand that other experts qualified as examiners of blood types perform independent tests under order of court, the results of which may be offered in evidence. The number and qualifications of such experts shall be determined by the court.
Appellant argues that the court is obliged, in all cases where blood tests are involved in a paternity question, to call .those persons who conducted the tests. He further claims that his stipulation to the admissibility of the results at issue was not a waiver of the Act’s protections. We find his argument to be without merit.
Appellant presents us with a simple matter of statutory construction, which is for the court’s resolution. Commonwealth, Higher Education Assistance Agency v. Abington Memorial Hospital, 478 Pa. 514, 387 A.2d 440 (1978). He emphasizzes that Section 6134 uses mandatory language when it states that “experts shall be called by the court.” However, it has long been the rule in Pennsylvania *85that the word “shall,” although usually mandatory or imperative when used in a statute, may nonetheless be directory or permissive, depending upon the Legislature’s intent; we ascertain this intent after reviewing the entire act, its nature, object and purpose, the respective consequences of various constructions of the particular statute, and after determining whether the action allegedly mandated by the statute is the essence of the thing to be done pursuant to it. Francis v. Corleto, 418 Pa. 417, 211 A.2d 503 (1965); Division 85, Amalgamated Transit Union v. Port Authority of Allegheny County, 417 Pa. 299, 208 A.2d 271 (1965); Prichard v. School District of Willistown Township, 394 Pa. 489, 147 A.2d 380 (1959); Pennsylvania R. Co. v. Board of Revision of Taxes, 372 Pa. 468, 93 A.2d 679 (1953); In re Nomination Papers of American Labor Party, 352 Pa. 576, 44 A.2d 48 (1945); National Transit Co. v. Boardman, 328 Pa. 450, 197 A. 239 (1938); Commonwealth v. Kowell, 209 Pa.Super. 386, 228 A.2d 50 (1967); Wielebinski v. Unemployment Compensation Board of Review, 197 Pa. Super. 292, 178 A.2d 783 (1962); County of Allegheny v. Pennsylvania Public Utility Commission, 192 Pa.Super. 100, 159 A.2d 227 (1960); Borough of Pleasant Hills v. Carroll, 182 Pa.Super. 102, 125 A.2d 466 (1956) (allocatur denied); Turner v. Unemployment Compensation Board of Review, 163 Pa.Super. 168, 60 A.2d 583 (1948); Appeal of Baldwin, 153 Pa.Super. 358, 33 A.2d 773 (1943); Kuzmen v. Kamien, 139 Pa.Super. 538, 12 A.2d 471 (1940). See also Commonwealth v. Hess, 270 Pa.Super. 501, 411 A.2d 830 (1979), appeal dismissed, 499 Pa. 206, 452 A.2d 1011 (1982); Commonwealth, Human Relations Commission v. Transit Casualty Insurance Co., 478 Pa. 430, 387 A.2d 58 (1978); Sohmer v. Sohmer, 318 Pa.Super. 500, 465 A.2d 665 (1983); Fireman’s Fund Insurance Co. v. Nationwide Mutual Insurance Co., 317 Pa.Super. 497, 464 A.2d 431 (1983).
In particular, where a statute’s mandatory language pertains to the action of a court, it is usually a grant of authority. Anderson’s Appeal, 215 Pa. 119, 64 A. 443 *86(1906); Becker v. Lebanon & M. St. Ry. Co., 188 Pa. 484, 41 A. 612 (1898). Compare Morrison v. Unemployment Compensation Board of Review, 141 Pa.Super. 256, 15 A.2d 391 (1940) (statute purporting to require a deliberative body to render a discretionary decision within a stated time will be construed to be directory). The statute at issue here clearly concerns the power of the court, by presuming to oblige the court to call specified witnesses. It therefore can be construed on this basis alone as merely granting the court the authority to do so.
In addition, the intent and purpose of the Act are twofold. First, the Legislature believed that admission of blood test evidence would be helpful in suits where paternity is an issue, because these tests permit scientifically reliable exclusion of a given man from the group of those who could be a certain child’s father. See Hummel v. Smith, 301 Pa.Super. 276, 286-87, 447 A.2d 965, 970 (1982) (Beck, J., concurring). However, Section 6134 seeks to protect putative fathers from adverse determinations based on blood test results not sufficiently reliable or adequately administered, and from the undue impression which “expert” evidence can make on a trier’s mind. The Act’s purpose is thus the same as the rule for expert testimony: to allow qualified “opinion” testimony in order to explain to the trier a subject matter which is beyond the experience and comprehension of the ordinary layman. See In re Japanese Electronic Products Antitrust Litigation, 723 F.2d 238 (3d Cir.1983); Zenith Radio Corporation v. Matsushita Electric Industrial Co., Ltd., 505 F.Supp. 1313 (E.D.Pa.1980); Hamil v. Bashline, 481 Pa. 256, 392 A.2d 1280 (1978); Reardon v. Meehan, 424 Pa. 460, 227 A.2d 667 (1967); Swartz v. General Electric Co., 327 Pa.Super. 58, 474 A.2d 1172 (1984). Where the expert witness performed the test or experiment at issue, as is the case under Section 6134, calling him to testify allows a party to inquire into the circumstances surrounding the test, the factors influencing its result, the variables which could affect the result, and the procedures used in recording and preserving the result. *87Parties are thus protected from any prejudice which may occur from the admission of scientific data which was not accurately gathered, analyzed or recorded.
However, we disagree with appellant that Section 6134 requires the court to call the described experts in all cases. First, the Act itself allows paternity determinations to be made without blood tests. Section 6133 states that “[i]f any party refuses to submit to such tests, the court may resolve the question of paternity, parentage or identity of a child against such party, or enforce its order if the rights of others and the interests of justice so require” (emphasis added). See also Smith v. Beard, 326 Pa.Super. 95, 473 A.2d 625 (1984). In addition, expert testimony is not the sole or paramount form of evidence used in paternity cases. Section 6132(b)(3), governing the use of blood tests in criminal proceedings, allows the court to direct a verdict for the defendant “upon the conclusions of all the experts under the provisions of Section 6136 (relating to effect of test results), otherwise the case shall be submitted for determination upon all the evidence” (emphasis added). Section 6136, in turn, provides that “[i]f the experts disagree in their findings or conclusions, the question shall be submitted upon all the evidence” (emphasis added).
These sections of the Uniform Act demonstrate the Legislature’s second intent, that the trier of fact decide paternity questions on all the evidence, not just on the pronouncements of experts. This is true even in a criminal prosecution, where the burden of proof is far higher and the defendant has such significant interests at stake. Logically, a “trier of fact” would be unnecessary in paternity cases if the verdicts were to be reached by the witnesses.
One final consideration supports our conclusion that Section 6134 does not mandate the calling of experts in every paternity case.
Such a requirement would give the parties to a paternity case a protection unavailable to other litigants. The defendant in a paternity case is entitled without question to certain *88rights and safeguards. See Corra v. Coll, 305 Pa.Super. 179, 451 A.2d 480 (1982) (due process entitles indigent paternity defendant to appointed counsel); Parenti v. Parenti, 263 Pa.Super. 282, 397 A.2d 1210 (1979) (upon motion, party is entitled to court-ordered blood tests); but see Beard, supra (right to trial in paternity case is not absolute). However, as we will discuss more fully later in this opinion, a party may stipulate to the admission of a piece of evidence, thereby waiving the protections afforded by the rules of evidence. Under appellant’s construction of Section 6134, a party in a paternity case would be insulated from the waivers incurred by other litigants who stipulate to admissibility.
We conclude, from the rules of statutory construction and the text of the Uniform Act, that expert testimony on blood tests is not an absolute, unwaivable requirement in every paternity case. Rather, the need for it will arise from the particular circumstances of the litigation. Where the alleged father denies paternity and challenges the admission of the plaintiff’s scientific or medical evidence, experts appointed under Section 6134 will be called to testify. Here, however, appellant’s stipulation is a circumstance we must consider.
The Pennsylvania rule on stipulations is long-settled: parties may bind themselves, even by a statement made in court, on matters relating to individual rights and obligations, so long as their stipulations do not affect the court’s jurisdiction or due order of business. Foote v. Maryland Casualty Co., 409 Pa. 307, 186 A.2d 255 (1962); Foley Brothers, Inc. v. Commonwealth, Department of Highways, 400 Pa. 584, 163 A.2d 80 (1960); Stinner v. Stinner, 300 Pa.Super. 351, 446 A.2d 651 (1982); Zvonik v. Zvonik, 291 Pa.Super. 309, 435 A.2d 1236 (1981); Kardibin v. Associated Hardware, 284 Pa.Super. 586, 426 A.2d 649 (1981); Marmara v. Rawle, 264 Pa.Super. 229, 399 A.2d 750 (1979); Chamberlin of Pittsburgh, Inc. v. Fort Pitt Chemical Co., 237 Pa.Super. 528, 352 A.2d 176 (1975) (allocatur denied). Stipulations to the admissibility of evidence are *89common. They do not affect jurisdiction, nor interfere with judicial business or convenience; instead, they aid the court by saving it time which would otherwise be spent on determining admissibility.
The courts employ a contracts-law analysis to interpret stipulations, so that the intent of the parties is controlling. Longenecker v. Matway, 315 Pa.Super. 411, 416, 462 A.2d 261, 263 (1983). The language of a stipulation, like that of a contract, is construed against the drafter. See Central Transportation, Inc. v. Board of Assessment Appeals of Cambria County, 490 Pa. 486, 417 A.2d 144 (1980). The court will hold a party bound to his stipulation: concessions made in stipulations are judicial admissions, and accordingly may not later in the proceeding be contradicted by the party who made them. Tops Apparel Manufacturing Co. v. Rothman, 430 Pa. 583, 587, 244 A.2d 436, 438 (1968); Light v. Miller, 303 Pa.Super. 527, 530, 450 A.2d 51, 53 (1982). See also Cole v. Altieri, 534 F.Supp. 165 (E.D.Pa.1981); Alley v. Comella, 241 F.Supp. 1016 (W.D.Pa.1965); Dale Manufacturing Co. v. Bressi, 491 Pa. 493, 421 A.2d 653 (1980); In re Estate of Monheim, 451 Pa. 489, 304 A.2d 115 (1973); Prudential Property & Casualty Insurance Co. v. Falligan, 335 Pa.Super. 195, 484 A.2d 88 (1984); Aetna Electroplating Co., Inc. v. Jenkins, 335 Pa.Super. 283, 484 A.2d 134 (1984); Hachick v. Kobelak, 259 Pa.Super. 13, 393 A.2d 692 (1978); Commonwealth v. Barksdale, 219 Pa.Super. 444, 281 A.2d 703 (1971) (allocatur denied).
Applying these rules, we find that appellant drafted the stipulation at issue by way of three separate statements at the paternity hearing. Appellant requested a continuance so that blood tests could be performed, and the Commonwealth 3 agreed:
[Assistant District Attorney]:
*90All right. And we are willing to agree that if he has it done it is admissible, the findings are admissible in court without any chain of custody, et cetera, and he has agreed to say—
[Appellant’s counsel]:
We would so stipulate, not that they are dispositive, but rather that they are admissible for the Court to draw such inference.
When appellee moved to admit the test results, the following discussion occurred:
[Appellant’s counsel]:
As indicated earlier in the record, we have no objection to the admissibility of the test, with this specific proviso: that we believe that it is a matter of statistical evidence as to the proper interpretation of the results. And absent testimony by an expert witness, these results do not have a legal significance.
[The Court]:
All right now. Do I understand that there is no objection to the marking of the HLA blood studies result as P-1, and the birth record P-2? And there is further no objection that they be admitted into evidence. Is that correct ... ?
[Appellant’s counsel]:
Yes, Sir.
At the close of appellee’s case, appellant moved to dismiss, stating in part:
[Appellant’s counsel]:
In addition, Your Honor, we would submit, again absent proper statistical evidence as to the validity of the HLA paternity testing report, its meaning is at best questionable. However, if there had been a statistician offered by the Commonwealth to explain to the Court the significance of this, we believe that upon cross-examination a number of important things would have developed____
*91Appellant concedes that he did not object to admission of the test report. However, he argues that the results, although admissible, were meaningless without expert testimony. Analogizing the results to business records, he further argues that conceding admissibility does not waive the requirement of a proper evidentiary foundation.
Appellant confuses the meaning of admissibility. Admissibility is determined not for a class of documents, but for each individual document, and proper foundation is a part of that determination. Hence, when a party concedes admissibility, the need for showing a proper foundation disappears. In Edwards v. Donley, 223 Pa.Super. 71, 297 A.2d 149 (1972) (allocatur denied), the defendant stipulated to the admissibility of the plaintiffs medical bills, but objected at the close of the plaintiffs case to their introduction. This Court held. that the stipulation relieved the plaintiff of the burden he would otherwise have carried before the bills could be admitted. Id., 223 Pa.Superior Ct. at 73-74, 297 A.2d at 150. While the defendant could reserve the right to question the completeness and reasonableness of the plaintiffs bills, that right was not exercised by merely objecting to their introduction. Id., 223 Pa.Superior Ct. at 75, 297 A.2d at 151.
Similarly, appellant’s “proviso” here regarding admission of the test results did not condition their admission on the presentation of expert testimony, nor did he properly object to it. His colloquy in support of the motion to dismiss raised no legal arguments against admission of the results, but rather attacked their value, calling them “questionable” without statistical evidence and claiming that cross-examination would have revealed several weaknesses in their merit. Finally, appellant objects to the hearing court’s “misuse” of the test results. That “misuse” was simply the court’s decision in favor of appellee, based in part on the test results which appellant agreed were admissible.
Appellant’s criticisms of the results go not to their legal admissibility but to the weight he believes a factfinder *92should accord them. Weight and admissibility are separate issues, and we will not find the hearing court in error for placing more weight on admissible evidence than appellant would prefer, especially where appellant himself agreed to its admission.
Appellant also claims that the hearing court, insofar as it considered the test report, violated appellant’s right to due process by denying him the right to confront and cross-examine relevant experts. In support, appellant cites Commonwealth ex rel. Valentine v. Strongel, 246 Pa.Super. 466, 371 A.2d 931 (1977), Wood v. Tucker, 231 Pa.Super. 461, 332 A.2d 191 (1974), and Goldberg v. Kelly, 397 U.S. 254, 90 S.Ct. 1011, 25 L.Ed.2d 287 (1970).
Appellant’s reliance on Valentine and Wood is misplaced. In Wood, the appellant in a child custody dispute argued that the trial court erred in relying on information dehors the record. This Court agreed, citing the rule that a court may not consider a report without examining the person who made it. 231 Pa.Super. at 463, 332 A.2d at 192. However, the cases following this rule require testimony by a report’s maker in child custody cases, given the crucial family interests at stake and the court’s paramount duty to discern and safeguard the best interest of the child. Robert H.H. v. May L.H., 293 Pa.Super. 431, 439 A.2d 187 (1982); In re Custody of White, 270 Pa.Super. 165, 411 A.2d 231 (1979). We did note in Wood that the use of information dehors the record denies a litigant his right to the in-court presentation of evidence and the opportunity to confront and cross-examine adverse witnesses. 231 Pa.Super. at 463-64, 332 A.2d at 192.
In Valentine, the petitioner raised the issue appellant raises now, that the 1961 Uniform Act required testimony by, including cross-examination of, experts. The experts in Valentine had sent written reports to the court and the parties, but presented no testimony at trial. Citing Wood, we held that, because of this,
there is absolutely no evidence in the record of the occurrence or result of any blood test. In its opinion the *93lower court stated that on the basis of blood tests performed, appellant could not be excluded as the father. It is apparent from the trial court’s opinion that it considered the blood tests prior to making its decision. Clearly it was error for the trial court to use evidence dehors the record to make its determinations.
246 Pa.Super. at 470, 371 A.2d at 933. We did not in Valentine reach the issue of whether the Uniform Act’s provision for expert witnesses is mandatory.
Both Wood and Valentine are distinguishable from the instant case. In both of those cases, the trial court considered evidence which was not in the record and therefore denied the appellants their right to confrontation and cross-examination. See also Coble v. Coble, 323 Pa.Super. 445, 447-48, 470 A.2d 1002, 1003-04 (1984); Shaffer v. Gaal, 312 Pa.Super. 399, 458 A.2d 1020 (1983). Here, by contrast, the test results were on record, pursuant to the stipulation and the reading of them into the record by appellee’s counsel.
We recognize that appellant has procedural and substantive rights. See Beard, Corra and Parenti, supra. However, a party may waive constitutional rights designed for his benefit. Kardibin, 284 Pa.Super. at 600, 426 A.2d at 656-57. The right to confront and cross-examine does not require that the parties in every case cross-examine each adverse witness, but that they have the opportunity to do so. Goldberg, 397 U.S. at 269, 90 S.Ct. at 1021, 25 L.Ed.2d at 300. This right may therefore be waived, even in a criminal case. See Commonwealth v. Harmes, 255 Pa.Super. 147, 386 A.2d 551 (1978). Appellant had the required opportunity to confront and cross-examine the technicians who administered and analyzed the blood tests and reported their results. That he forewent this opportunity is no error on the part of the hearing court.
Nor do we find merit in appellant’s contention as to what “cross-examination” of a statistician would have revealed about the reliability of HLA tests. Assuming appellant meant a statistician distinct from the persons who *94performed the test,4 we find no indication in the record that he was prevented from introducing testimony, by an expert of his own, on this subject. Appellant bases this argument on his claim that the hearing court, by admitting the evidence to which he had stipulated, violated his right to confrontation and cross-examination. A party may not complain when he waives his right to present evidence in his favor by choosing not to do so. See Lowenschuss v. Lowenschuss, 323 Pa.Super. 381, 470 A.2d 970 (1983).
Appellant next argues that he is entitled to the benefit of our holding in Turek, supra, which was decided after the hearing of the instant case. Given our decision on appellant’s first and third questions for review, we need not reach this issue. However, we will consider it for the purpose of encouraging competent appellate advocacy.
In Turek, as in the case at bar, the defendant in a paternity suit requested blood tests, and stipulated that the results were admissible. He then objected to the introduction of the results and of expert testimony. We held that HLA test results were “admissible under the current state of the law” as some evidence of paternity. 312 Pa.Super. at 160, 458 A.2d at 563. We also set forth some foundation guidelines which “[t]he party seeking to affirmatively use the HLA results” should show before those results are admitted. Id., 312 Pa.Superior Ct. at 164, 458 A.2d at 565. However, we did not consider the effect of the parties’ stipulation on this requirement.
Appellant cannot insist that he is “entitled” to the Turek holding. First, Turek allowed the admission of HLA test results as some evidence of paternity, where appellant *95challenges their admission in his case. Second, Turek did not announce that HLA results were admissible where they had not been before, but stated rather that they were admissible under current law.5 Appellant himself admits that we decided Turek on the basis of existing law; he concludes that therefore Turek need not be held retroactive to apply to the instant case and adds that, because he “has agreed all along” that the results are admissible, the trial court’s comment on Turek concerned a “non-issue.”6
Third, appellant emphasizes the Turek Court’s comment that “it is axiomatic that a foundation must be laid” before evidence is admitted. 312 Pa.Super. at 164, 458 A.2d at 565. Appellant then states that the foundation requirement is not a new rule of law, and again concludes that we need not hold Turek retroactive.
Appellant’s only genuine ground for seeking retroactive application of Turek seems to be that decision’s list of guidelines for a proper foundation for HLA results. However, he once more states that retroactivity is unnecessary, because in his case no foundation was presented and ample precedent requires a foundation. He nonetheless concludes that he was “entitled” to Turek and that the hearing court’s refusal to apply its holding was erroneous. For the reasons above set forth, we reject that conclusion.7
Finally, appellant asserts that the hearing court’s finding of paternity was against the weight of the credible evidence. In reviewing this argument, we must defer and *96give great weight to the hearing court’s appraisal of credibility, since that court observed the witnesses during their testimony. Commonwealth ex rel. Ermel v. Ermel, 259 Pa.Super. 219, 223, 393 A.2d 796, 798 (1978); Burston v. Dodson, 257 Pa.Super. 1, 390 A.2d 216 (1978); In the Interest of Clouse, 244 Pa.Super. 396, 368 A.2d 780 (1976) (allocatur denied). We may disregard or overrule the hearing court’s determinations of credibility and the weight of the evidence only in clear cases, when we find that those determinations were manifestly erroneous, arbitrary and capricious, or flagrantly contrary to the evidence. Delahanty v. First Pennsylvania Bank, N.A., 318 Pa.Super. 90, 464 A.2d 1243 (1983); Glickman Real Estate Development v. Korf 300 Pa.Super. 202, 446 A.2d 300 (1982); Shacreaw v. Shacreaw, 248 Pa.Super. 223, 375 A.2d 68 (1977); Leibowitz v. Ortho, 224 Pa.Super. 418, 307 A.2d 449 (1973). In addition, the plaintiff in a civil paternity suit need prove the claim only by a preponderance of the evidence. Commonwealth ex rel. Johnson v. Peake, 272 Pa.Super. 340, 415 A.2d 1228 (1979); Commonwealth ex rel. Lonesome v. Johnson, 231 Pa.Super. 335, 338, 331 A.2d 702, 704 (1974).
Beside passing on credibility, the hearing court considered its examination of the child and comparison of her traits to appellant’s, a valid comparison in paternity cases. Lonesome, 231 Pa.Super. at 338, 331 A.2d at 704.
Upon review of the record, we find that the hearing court’s determinations on credibility were not manifestly erroneous, arbitrary and capricious, or flagrantly contrary to the evidence.
AFFIRMED.
BECK, J., files a dissenting opinion.

. Pa.R.Civ.P. 1910.15 allows appeal of “any issue of paternity” from a final order of support.

. Act of July 9, 1976, P.L. 586, No. 142, effective June 28, 1978, as amended 42 Pa.C.S.A. §§ 6131-6137 (originally enacted as Act of July 13, 1961, P.L. 587, No. 286) (hereafter “Uniform Act”).

. The Commonwealth appeared in the case pursuant to 42 Pa.C.S. § 6711 (the Civil Procedural Support Law), which states that the district attorney "shall at all times aid in the enforcement of the duty of support.” See 42 Pa.C.S. §§ 6701-6713.

. In spite of appellant’s argument based on Section 6134, which refers to the "experts” who actually took, analyzed and reported the blood tests, appellant is unclear whether he wanted testimony from these persons or simply from someone qualified to testify about HLA tests and the statistical probabilities involved in their interpretation. His third question presented refers to "blood test examiners or a statistician” (emphasis added). In addition, Section 6134 allows the party who requested blood tests to “demand” that other, independent tests be made for comparison. Appellant waived this provision by accepting the first test as probative of paternity.

. Before Turek, two separate opinions from our Court focused on the desirability of HLA testing over the former red-blood cell typing method. See Hummel, 301 Pa.Super. at 285, 447 A.2d at 970 (Beck, J., concurring), and In re Mengel, 287 Pa.Super. 186, 200-01, 429 A.2d 1162, 1170 (1981) (Spaeth, J., concurring).

. The trial court’s “comment” on Turek was simply that that case was decided after defendant’s post-trial motions, and that, until it is held to be retroactive, it does not affect the present case.

. We also caution counsel that appellate advocacy is hindered when appellate briefs raise arguments and then dismiss them. Issues should be raised only when counsel in good faith believes that they are meritorious; otherwise, neither the interests of judicial economy nor those of the attorney-client relationship are well-served.
