Reason for recall
The potential for falsely depressed Intact PTH patient results at the low end of the assay range, less than or equal to 50 pg/mL (less than or equal to 5.3 pmol/L), when using specific lots identified by the firm on the IMMULITE 2000/IMMULITE 2000 XPi systems. The bias is observed in both serum and plasma samples.
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.
