The Acute Interference of Biotin in Blood Analysis

Biotin, also known as vitamin B7, is a water-soluble vitamin. It is essential for several metabolic processes in the body, including glucose, lipid, and protein metabolism, as it acts as a coenzyme in several carboxylation reactions. Biotin, available as an over the counter supplement, is widely used to improve nail and hair growth. The use of biotin supplements can interfere with various laboratory tests, due to the use of the streptavidin-biotin interaction in several immunoassays. We therefore wish to investigate acute impact of biotin supplementation on various laboratory assays, with focus on the immediate post-ingestion effects and the time frame in which biotin interference is most pronounced.
