Monitoring Accuracy – AMP Hormones

At a glance

The measurement accuracy of laboratory tests used routinely in patient care, research, and public health studies can change over time. It is important to note these changes so that correct measurement results are reported. ob体育 monitors the accuracy of measurements performed in routine laboratories over time.

ob体育 Accuracy-Based Monitoring Program (AMP)

Using the following processes, ob体育's Accuracy-Based Monitoring Program (AMP) helps laboratories monitor the accuracy of their own laboratory tests over time:

  1. ob体育 provides participants samples with reference values unknown to the participant.
  2. Participants measure these samples weekly along with their regular patient or study samples.
  3. Participants report the results of their sample measurements to ob体育.
  4. Using established statistical assessment procedures, ob体育 compares participants' results to the actual concentrations determined with the ob体育 reference measurement procedures.
  5. ob体育 provides participants with quarterly assessment reports.

Accuracy-based blinded quality control program

Using the processes below, ob体育's laboratory assessment programs help researchers monitor the accuracy of their contract laboratories' tests:

  1. ob体育 provides researchers with "blinded" quality control samples, meaning the quality control samples cannot be differentiated from the study samples. These are vials with serum samples an investigator adds to batches of vials with study samples. These vials are labeled in the same manner as regular study samples. The number of quality control samples used, and the frequency with which they are added to the study samples, can vary depending on the needs and requirements defined by the investigator.
  2. The laboratory measures the samples and reports the results to the investigator.
  3. The investigator compares the reported values with the actual concentrations using ob体育's reference method.
