BTKK | Test | BTKK | Bruton's [NAME] (BTK) Genotype, Known Mutation | BTK Gene, Known Mutation | Polymerase Chain Reaction (PCR) Followed by DNA Sequence Analysis (PCR is utilized pursuant to a license agreement with Roche Molecular Systems, Inc.) | Lavender-top (EDTA) Tube: EDTA |  |  | 3 | mL | Multiple whole blood EDTA genotype tests can be performed on a single specimen after a single extraction. See Multiple Whole Blood EDTA Genotype Tests in Special Instructions for a list of tests that can be ordered together.  Container/Tube: Lavender top (EDTA) [NAME]: 3 mL Collection Instructions: Send specimen in original tube. Additional Information: 1. Ordering physician name and phone number are required. 2. Bone marrow transplants will interfere with testing. Call Mayo Medical Laboratories at [PHONE] or [PHONE] for instructions. 3. Transfusions will interfere with testing for up to 4 to 6 weeks. DNA obtained from white cells may not provide useful information for patients who received a recent transfusion of blood that was not leukocyte-reduced. Wait 4 to 6 weeks until transfused cells have left the patient's circulation before drawing the patient's blood specimen for genotype testing. Forms:  1. Bruton's [NAME] (BTK) Genotype Patient Information Sheet (Supply T620) in Special Instructions. 2. New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instruction. | 0.3 mL | Hemolysis	NA Thawing	Warm OK; Cold OK Lipemia	NA Icterus	NA Other	NA | An interpretive report will be provided. | Monday | 28 days | 42 days | 1 | 81479 |  |  |  |  | Rochester

Include physician's name and phone number with  		  the specimen. 2.     Bone marrow transplants will interfere with testing.  		For bone marrow transplant patients, buccal cells  		should be provided from the recipient to obtain an  		accurate genotype. 3.     Transfusions will interfere with testing for up to 4 to 6 		weeks.
