Why it was recalled

The Test cup lot F level 1 low-quality control results values for the device were lower than expected on the Automated Immunoassay Analyzer (AIA) which could cause falsely elevated or falsely low total testosterone results. Such erroneous test results may lead to additional testing/diagnostic interventions and in limited cases, may lead to a delay in diagnosis and/or initiation of unnecessary or incorrect clinical treatment measures.

This product could cause temporary or reversible health problems — stop using it.
