LOT 867175, UDI (B)(4), MANUFACTURING DATE 19APR2024, EXPIRATION DATE 28FEB2026. INVESTIGATION FOR LOT 871699: AS PART OF AN INVESTIGATION INTO PRELIMINARY FALSE REACTIVE RESULTS, ABBOTT FOUND THAT FOR KIT LOT 871699, THE ROOT CAUSE OF THE RESULTS WAS DUE TO A SUBCOMPONENT USED IN THE MANUFACTURE OF DETERMINE HIV-1/2 AG/AG COMBO. THE ISSUE HAS BEEN ISOLATED TO SPECIFIC LOTS OF THE SUBCOMPONENT, WHICH WERE USED TO MANUFACTURE SPECIFIC TEST KIT LOTS. THE NECESSARY ACTIONS TO PREVENT RECURRENCE HAVE BEEN TAKEN, AND THE CORRECTION OF PRODUCT IN THE FIELD WAS CONDUCTED.

THE LOT MET THE REQUIRED RELEASE SPECIFICATIONS.
