We note that the laboratory provided no documentation to indicate that the inaccurate calculations were reviewed or that INR calculation using different lot numbers of Dade Innovin were reviewed for accuracy. In addition, we found that the laboratory did not provide documentation to ensure that PT/INR results reported from calculations were, and would continue to be, accurate.

To ensure the deficient practice does not recur, the laboratory indicated that quarterly audits will be performed and suggested that the audits results would be reviewed within the laboratory's QMPI Program. However, the laboratory did not establish the procedure by which these quarterly audits are to be conducted. In its submission, the laboratory indicates that a "tracer audit may [emphasis added] be used," but did not provided a protocol for a "tracer audit," the means by which a "tracer audit" would be documented, and whether the results of a "tracer audit" would be the information reviewed by the QMPI Program.

The laboratory failed to adequately address this deficiency and provide acceptable evidence of correction consisting of the required documentation and information set forth above and in our January 25, 2016 letter.
