Order Total Glutathione TestGlutathione is a tripeptide composed of glutamate, cysteine, and glycine, and it participates in antioxidant defense, detoxification reactions, and the regulation of cellular redox balance. A Total Glutathione Test quantifies the combined pool of reduced glutathione (GSH) and oxidized glutathione (GSSG) in a specimen, offering a broad view of this molecule's status rather than distinguishing between its two forms.
About Total Glutathione Test in Tempe
Total glutathione reflects the sum of its reduced and oxidized forms, a distinction that matters when interpreting the result.
Reduced glutathione (GSH) is the predominant intracellular form and serves as a major thiol antioxidant, while oxidized glutathione (GSSG) forms when GSH donates electrons and becomes dimerized. Because the two forms interconvert, a total glutathione measurement captures the overall pool without resolving the redox ratio between them.
Specimens for total glutathione testing are typically blood, plasma, or erythrocytes, though other matrices may be used in research or specialized clinical settings. Glutathione concentrations can differ markedly by specimen type and by the handling conditions before analysis, since the molecule is susceptible to oxidation and degradation ex vivo.
Results are reported as a concentration in the units specified by the performing laboratory, and reference intervals are method-dependent. A total glutathione value outside a laboratory's stated range may prompt consideration of nutritional, metabolic, oxidative, or hepatic factors, but it is not by itself diagnostic and is best interpreted alongside the broader clinical picture.
