Each laboratory performing tests and analysis under this subchapter will be subject to a quality assurance program evaluation at least annually, and more often if deemed necessary by the Deputy Administrator. Such evaluation will include:
A review of the adequacy of quality control measures taken by the laboratory for the standardized method of analysis for a commodity and its related products;
A review of the laboratory methodologies and procedures;
A review of records for the calibration and maintenance of equipment;
A review of records documenting sample handling;
The evidence of quality control records;
The evidence of correct reporting and determination of analytical data.
A laboratory will receive a quality assurance report following the review. This evaluation will address any necessary improvements to the laboratory program(s) being examined.
