App-derived interpretation

Unknown reason.no_named_rule · v1.0.0
The product was recalled because stability evaluation of the lots indicated a decrease in reactivity that could lead to a potential false-negative result interpretation. The issue was identified by the firm after failing to meet lot requirements for potency. The lot release error was discovered on October 08, 2021, after a failed potency test was determined during 6-month stability evaluation of retention material for the lots. The subsequent manufacturing investigation, which included a review of the lot release potency documentation, found that the initial lot release potency test for the lot was misinterpreted.

These labels are deterministic app interpretations, not FDA categories.
