This proficiency program is designed to test analytes requested for a general urine screen procedure done either manually or by instrument. Results are reported semi-quantitatively.
Specimens are prepared as a synthetic buffered base to which the above analytes are added.
Specimens are stored and shipped frozen to participants. Urine pregnancy proficiency testing covers only qualitative urine screening for pregnancy. This is also a high volume test in most clinical laboratories. Women are routinely screened for detection of early pregnancy and before emergency procedures harmful to a fetus are carried out.
