Quality Control

All laboratories that perform analysis under a Level 2 or Level 3 study plan shall implement a quality assurance program. There must be written documentation for all elements of the quality assurance program in the form of a quality assurance manual (QAM), a quality assurance plan (QAP), or a quality assurance project plan (QAPP). Guidelines for the content of this written documentation have been provided in the administrative rules for the Credible Data Program:

The Qualified Data Collector who submits the study plan is responsible for ensuring that the required written documentation of the quality assurance program exists.
