United StatesThe IMMULITE 2000 Intact PTH assay (Test Code iPT) from Siemens Healthcare Diagnostics—SMN 10381441 (Catalog L2KPP2, UDI-DI 00630414961910) and SMN 10381442 (Catalog L2KPP6, UDI-DI 00630414961927), lots 385, 387, 388, and 389—is affected. Siemens recalled these lots because they can produce falsely depressed intact PTH patient results at or below 50 pg/mL (≤5.3 pmol/L) on IMMULITE 2000/IMMULITE 2000 XPi systems; the bias occurs in both serum and plasma samples.
