Abstract
A calibrator composed of 90% prostate-specific antigen-alpha 1-antichymotrypsin (PSA-ACT) and 10% free PSA reduces the variation in control serums with widely divergent amounts of free PSA, from a mean of 28% among nine different assays to 9% after recalibration. The lyophilized form of the Stanford 90:10 calibrator is stable and therefore an excellent candidate for international standardization of PSA assays.Entities:
