Reason for recall

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.

Lead and other heavy metals accumulate in the body. Children are most at risk; even low levels can affect development.
