Siemens Recalls Immulite Assays Due to Biotin Interference Risk
Siemens Healthcare Diagnostics is recalling certain IMMULITE assays because the instructions for use do not list the biotin concentration that causes interference, posing a risk of inaccurate test results.
What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: The recall is FDA Class II, but the hazard involves a risk of inaccurate diagnostic results due to biotin interference. While no illnesses are reported, incorrect test results for critical markers like Thyroglobulin or Vitamin B12 pose a significant risk of harm if misinterpreted clinically.
Plain-English summary
Siemens Healthcare Diagnostics, Inc. is recalling specific lots of IMMULITE assays, including 3gAllergy Specific IgE, anti-HBc, BR-MA (CA15-3), CEA, Folic Acid, Gastrin, OM-MA (CA125), Thyroglobulin, and Vitamin B12. The recall also affects the Dimension Vista CTNI, Dimension Vista MMB, Dimension Sirolimus, ADVIA Centaur FOL, and ADVIA Centaur aHBcM.
The issue stems from the instructions for use for these products not currently listing the concentration of biotin that does not interfere with test results. Consequently, these assays are susceptible to interference from biotin, which may lead to inaccurate patient test results.
The affected products were distributed nationwide in the United States and in Canada, Mexico, and Thailand. The recall covers lot codes 0289, 0290, 0291, D0289, D0290, and D0291 for the IMMULITE/IMMULITE 1000 (LKTY1(D)) and IMMULITE 2000/IMMULITE 2000 XPi (LKTY2(D)) systems.
Healthcare providers and laboratories using these assays should be aware of this potential interference when interpreting biotin-related tests.
