FDA has released a safety communication (November 2019) to alert health care professionals, lab personnel and consumers to the possible interference of biotin (vitamin B7, Vitamin H, Coenzyme R) with common, clinically significant lab tests, specifically troponin.
Be aware that many lab tests, including but not limited to cardiovascular diagnostic tests and hormone tests, that use biotin technology are potentially affected, and incorrect test results may be generated if there is biotin in the patient’s specimen
Communicate to the lab conducting the testing if your patient is taking biotin
If a lab test result does not match the clinical presentation of your patient, consider biotin interference as a possible source of error
Report to the lab test manufacturer and the FDA if you become aware of a patient experiencing an adverse event following potentially incorrect laboratory test results due to biotin interference
