Biotin interference in clinical immunoassays
WebJul 4, 2024 · Biotin interference in immunoassays is not expected with normal dietary intake of biotin, with interfering doses varying from 1.5 to 300 mg/d as reported (56, 60, 63). Therefore, a practical and useful way to identify this interference is to address the question of whether the patient is taking biotin. WebThe risk of biotin interference extends to assays critical to internal medicine, such as tests for anemia, malignancies, autoimmune and infectious diseases, and cardiac damage, said Earle W. Holmes, PhD, DAACC, director of the Loyola University Medical Center special chemistry, immunoserology, and endocrinology laboratories in Hines, Illinois.
