Key points
The certification process ensures that the method in question is accurate and reliable. Ongoing certification also assures end users that the product stays accurate and reliable. Many clinical laboratories rely on test manufacturers to maintain certified methods.
List of HoSt certified participants
Certified manufactures are those that meet ob体育’s analytical performance criteria. ob体育 issues certificates for each certified analytical system evaluated. The date used on the certificate as the “Date of Certification” indicates when the laboratory data were compiled and statistically analyzed at ob体育.
After meeting acceptance analytical performance for four consecutive quarters, a participant is certified. The certification is valid for one year. After four consecutive quarters, participants are evaluated quarterly for certification.
Testosterone in serum
The following laboratories have successfully passed the performance criterion ±6.4% mean bias to the ob体育 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 ensure 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 ob体育 HoSt Program to certify each lot of reagents, or to issue certification beyond the measurement range of 2.50-1,000 ng/dL, at this time.

Estradiol in serum
The following laboratories have successfully passed the performance criteria of ±12.5% mean bias (for samples >20 pg/mL) and ±2.5 pg/mL absolute bias (for samples ≤20 pg/mL) to the ob体育 Estradiol Reference Method in serum over the concentration range of 1.92-209 pg/mL. 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 ensure 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 ob体育 HoSt Program to certify each lot of reagents, or to issue certification beyond the measurement range of 1.92-209 pg/mL, at this time.

Accuracy-Based Monitoring Program (ob体育 AMP) for hormones
The following clinical and research laboratories have documented traceability to the ob体育 Clinical Reference Laboratory by meeting performance criteria used by the AMP for total testosterone in males and females (TT) and/or total 25-hydroxyvitamin D (VD).
The following list includes the laboratory name, location of the laboratory, analyte, measurement principle, assay identifier, analysis dates, and the status of the assay in the ob体育 Hormone Standardization Program (ob体育 HoSt) and/or the ob体育 Vitamin D Standarization-Certification Program (ob体育 VDSCP).
