Biomarker Reference · Zn
Intracellular Zinc (Zn) is a clinical biomarker used in comprehensive-panels assessment. Zinc is a cofactor for hundreds of metalloenzymes and a structural component of zinc-finger transcription factors, essential for immune function, protein synthesis, and antioxidant defence. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Zinc is a cofactor for hundreds of metalloenzymes and a structural component of zinc-finger transcription factors, essential for immune function, protein synthesis, and antioxidant defence. Cellular assays measure functional zinc availability in lymphocytes, which can diverge from serum zinc in inflammatory or catabolic states.
Zinc deficiency impairs cell-mediated immunity, causes dermatitis and diarrhoea, and delays wound healing. Intracellular zinc is used in functional testing to identify marginal deficiency, particularly in patients with chronic infection or malabsorption, though the correlation between lymphocyte zinc and clinical zinc status is not fully validated.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
