RCDR Laboratory Proficiency testing

As a part of the quality management system in RCDR, the laboratory is participating in Bio Rad Proficiency testing to quality assure laboratory results, in cycle 11 hemoglobin A1c program (BC80) RCDR laboratory classified in the best performance category among best performance group of 497 lab out of 1800 lab in international league and best performance category among 20 lab in national league out of 40 lab.

Each cycle consist of 12 unknown samples to be performed in specific date (One month interval) the results are compared against golden standard method (reference method).
Proficiency testing determines the performance of individual laboratories for specific tests or measurements and is used to monitor laboratories’ continuing performance.
Proficiency testing is also called interlaboratory comparison. As this term implies, proficiency testing compares the measuring results obtained by different laboratories

In a proficiency test one or more artifacts are sent around between a number of participating laboratories. Each laboratory measures the artifacts (e.g. a ring gage or a set of gage blocks) according to a given set of instructions and reports its results to the administrator.

The results reported by each laboratory for a measurand are compared to the reference value for that measurand.The reference value can be determined in various ways.The two most common ways are to use a reference laboratory or use the average of the values reported by the participants.

Proficiency testing involves a group of laboratories or analysts performing the same analyses on the same samples and comparing results. The key requirements of such comparisons are that the samples are homogenous and stable, and also that the set of samples analyzed are appropriate to test and display similarities and differences in results.
