  Dimension Vista Total Bilirubin (TBIL) Flex Reagent Cartridge; Siemens Material Number (SMN): 10445146;

  During manufacturing, the last three tests from the 160 test flex of lot 23206BA (wells 8 or 10) were processed on the Dimension Vista platform. There was an issue with the filling line which led to some wells to underfill in lot 23206BA. Calibrator, quality control (QC) and patient results could have been impacted.

  VITROS XT Chemistry Products TBIL-ALKP Slides

  Samples containing high levels of ALKP (or an interfering substance) could deplete the available substrate in the reagent layer of a VITROS ALKP Slide and not post the substrate deleption (DP) code, which may result in the System reporting an incorrect value (lower than the actual value), which may result in missed or delayed diagnosis of liver disease.
