Biomarker Reference · B5
Intracellular Vitamin B5 (Pantothenic Acid) (B5) is a clinical biomarker used in comprehensive-panels assessment. Pantothenic acid is the precursor of coenzyme A, essential for fatty-acid synthesis and oxidation, the tricarboxylic acid cycle, and acetylcholine synthesis. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Pantothenic acid is the precursor of coenzyme A, essential for fatty-acid synthesis and oxidation, the tricarboxylic acid cycle, and acetylcholine synthesis. Deficiency is rare because the vitamin is widely distributed in foods, but intracellular measurement is marketed to detect marginal insufficiency.
Frank deficiency causes fatigue, paresthesia, and adrenal insufficiency in experimental settings. Subclinical depletion is proposed to impair lipid metabolism and stress response, but evidence linking intracellular pantothenate to clinical outcomes is limited.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
