Limitations
This assay has not been licensed by the US Food and Drug Administration for the screening of blood, plasma, and tissue donors. Results should always be assessed in conjunction with the patient's medical history, clinical examination, and other findings. Serum specimens from individuals taking biotin supplements of more than 20 mg per day may have false-negative results due to interference. False-positive results may occur due to the presence of interfering substances. Methods may not detect all infected individuals. Interference from high titers of antibodies, streptavidin, or ruthenium can occur. Assay performance not established for certain populations or specimen types.
