In Ex. B and Ex. H, the submission includes lists of patient specimen accession numbers for which the laboratory intended to issue corrected test reports. The laboratory provided no documentation to indicate corrected reports were generated and issued.

Because the laboratory has not shown whether it can follow its own QC protocols, it is unclear whether the laboratory's quality assessment mechanisms can monitor the laboratory's corrective actions and ensure this deficient practice does not recur.

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.

Finding #9
The laboratory did not submit any documentation in the referenced exhibits related to an updated protocol for Alternative Assessment Procedures (AAP); therefore, we have concluded that the current protocol applies. The laboratory's submission did not include any documentation to explain why the laboratory did not follow its AAP protocol for the Theranos Proprietary System.

Because the laboratory has not shown whether it can follow its own AAP protocols, it is unclear whether the laboratory's quality assessment mechanisms can monitor the laboratory's corrective actions and ensure this deficient practice does not recur.

Finding #10
Ex. A, Tab 9 of the submission contains the protocol "Method Validation." Section 8.4 of this protocol, "Reference Intervals," states:

The reference intervals are established from a selected reference population. Typically, when both decreased and increased levels are clinically significant, it is defined as the interval between and including the lower and upper reference limits of the studies population. This is calculated as the central 95 percentile of the population distribution where the lower and upper reference limits are demarcated as the 2.5th and 97.5th percentiles of the underlying distribution of values. . . The reference intervals are used to establish expected level in health "normal" individuals. Values outside the reference range are considered "abnormal" or "high" or "low.

In Ex. E, Tab 1, the laboratory states:

[The] laboratory director decided to use medical decision limits based on national consensus. Accordingly, the following decision limits were displayed on all lab reports for Vitamin D. As noted in CLSI EP28-A3, "when decision limits determined by national or worldwide consensus exist, these limits, rather than reference intervals should be reported.
