Siemens Healthineers has confirmed through the internal investigation of customer complaints that the IMT diluent volume remaining (% remaining) does not decrease as expected on the Atellica® CI analyzer. The IMT module runs a standard a refresh sequence before processing samples if at least two minutes of inactivity have passed. IMT diluent is used by this sequence, however, the calculated diluent volume is not accurate, potentially leading to the IMT diluent being empty while still displaying that volume is remaining. In this case sodium (Na), potassium (K) and chloride (Cl) test results may be falsely elevated. quality control materials demonstrate the same behavior. Recall start date: November 6, 2024
