Standardized Measurement Procedures

Testosterone in Serum

The following laboratories have successfully passed the performance criterion of less than 6.4% mean bias to the CDC Testosterone Reference Method over the concentration range of 2.50-1,000 ng/dL. Laboratories are awarded Certificates for successfully completing bias testing using specific methods, reagent lots, calibrator lots and instrumentation. During the year it is the responsibility of the participant to insure that the results of their method remain consistent over time, throughout the year, between lots, and over the measurement range reported. It is not the intent of the CDC HoSt to certify each lot of reagents and beyond the measurement range of 2.50-1,000 ng/dL.
