Biomarker Reference · B2
Intracellular Vitamin B2 (Riboflavin) (B2) is a clinical biomarker used in comprehensive-panels assessment. Riboflavin is the precursor of flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), coenzymes for oxidation-reduction reactions in the mitochondrial respiratory chain, fatty-acid beta-oxidation, and xenobiotic metabolism. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Riboflavin is the precursor of flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), coenzymes for oxidation-reduction reactions in the mitochondrial respiratory chain, fatty-acid beta-oxidation, and xenobiotic metabolism. Lymphocyte riboflavin is offered as a surrogate for tissue FAD status.
Riboflavin deficiency classically causes angular stomatitis and glossitis but subclinical insufficiency may contribute to fatigue and impaired antioxidant capacity. Intracellular testing is used in functional medicine to identify marginal deficiency in individuals with normal serum riboflavin.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
