i-STAT hs-TnI Cartridge

Abbott has identified that lots beginning with A24, A25, B25, B26, C26, and D26 may have a reduced ability to mitigate certain forms of analytical interference, including macrotroponin and heterophile antibody-related interference, due to variability associated with the alkaline phosphatase component used during reagent manufacturing.  This issue may result in falsely elevated cardiac troponin I results.  There is no evidence that the issue has caused falsely low results.
