Official wording
Reason: Deterioration in performance of the Liquid Stable (LS) 2-Part HOMOCYSTEINE REAGENT resulting in under recovery. The manufacturer has indicated that the HOMOCYSTEINE REAGENT lot listed above shows deterioration in assay performance manifesting itself by under recovery of Homocysteine in Controls and Patient Samples. The cause of this deterioration has been attributed to a loss of reductant activity in Reagent 1. Testing performed indicated that the affected lot is at the limit of acceptable clinical performance. This observation was consistent across the reportable range of the assay. For this reason, do not continue to use affected reagent lot. Test data generated to date will be acceptable where validity control specifiCations have been met.
