Both CMS (42 CFR 493.1281) and the College of American Pathologists (TRM.31450 & COM.04250) require laboratories that use more than one method of testing a given analyte to have a system in place to compare those methods. Laboratories are required to check those methods against each other twice a year.
In a recent study, conducted at Moses H. Cone Memorial Hospital, the ALBAcheck® Competency Testing Kit from Quotient was incorporated into their comparability of methods protocol. The kit was shown to be a simple and convenient solution to complying with these requirements. To see the full poster (click here).
