Reason for recall

Siemens Healthcare Diagnostics confirmed over-recovery of samples with concentrations greater than 5.5 ng/mL with the IMMULITE/IMMULITE 1000 and IMMULITE 2000/IMMULITE 2000 XPi Androstenedione assays (LKAO1, L2KAO2). Siemens has determined that these lots are linear up to a concentration of 5.5 ng/mL, instead of 10 ng/mL as stated in the Instructions for Use (IFU). Quality Control materials at concentrations between 5.5 and 10 ng/mL will detect this issue.

Potency and specification recalls happen when a batch tests outside its approved limits for strength, purity or dissolution, which can mean the dose delivered is higher or lower than labelled.
