Biotin can significantly interfere with certain lab tests and cause incorrect test results, including false negative results (eg, falsely low troponin) or false positive results (eg, thyroid function tests appearing as Graves disease), possibly leading to inappropriate patient management or misdiagnosis (Bowen 2019; FDA Safety Communication 2019; Kummer 2016).
There are no adverse reactions listed in the manufacturer’s labeling.
• RDA values: Are not requirements, but are recommended daily intakes of certain essential nutrients.
• Laboratory test interaction: Biotin in blood or other samples taken from patients who are ingesting high levels of biotin from dietary supplements (including multivitamins, prenatal multivitamins, biotin supplements, and dietary supplements for hair, skin, and nail growth) can cause clinically significant incorrect lab test results. Some testing methods use biotin technology (eg, troponin, thyroid function tests, other hormone tests), which use biotin to bind to specific proteins that are measured to detect health conditions. An increase in the number of reported adverse events, including one death, related to biotin interference with lab tests has been reported. If a lab test result does not correspond with a patient's clinical symptoms, biotin interference should be considered as a possible source of error (Bowen 2019; FDA Safety Communication 2019).
Water soluble vitamins cross the placenta (IOM 1998).
