What is Intracellular Biotin (Vitamin B7)?

Biotin is a cofactor for carboxylase enzymes in gluconeogenesis, fatty acid synthesis, and branched-chain amino acid catabolism. Functional assays assess lymphocyte performance when biotin is rate-limiting.

Why is Intracellular Biotin (Vitamin B7) measured?

Biotin deficiency causes dermatitis, alopecia, and neurological symptoms. Functional testing is used in suspected deficiency due to malabsorption, biotinidase deficiency, or prolonged anticonvulsant or raw-egg-white consumption, where serum biotin may not reflect intracellular status.
