Biomarker Reference · Se
Intracellular Selenium (Se) is a clinical biomarker used in comprehensive-panels assessment. Selenium is incorporated into selenoproteins, including glutathione peroxidases and thioredoxin reductases, which are central to antioxidant defence and thyroid hormone metabolism. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Selenium is incorporated into selenoproteins, including glutathione peroxidases and thioredoxin reductases, which are central to antioxidant defence and thyroid hormone metabolism. Cellular assays measure functional selenoprotein activity when selenium is rate-limiting.
Selenium deficiency can cause cardiomyopathy (Keshan disease) and is associated with immune dysfunction and thyroid disorders. Intracellular selenium is offered as a marker of functional sufficiency in regions with marginal intake or in patients with malabsorption, though its incremental value over plasma selenium is uncertain.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
