Measures the body's master antioxidant — critical for detoxification, immune function, and cellular protection. Glutathione is the most abundant and important antioxidant produced by the human body. It plays a central role in detoxification (neutralizing free radicals, heavy metals, and environmental toxins), immune system regulation, DNA repair, and cellular energy production. Depleted glutathione levels are associated with accelerated aging, chronic fatigue, neurodegenerative diseases, liver disease, and increased susceptibility to infections. This test measures total glutathione in the blood. It is frequently ordered by longevity-focused clinicians, patients with chronic illness, and those monitoring their antioxidant status during detoxification protocols or supplementation with NAC (N-acetylcysteine) or liposomal glutathione. **Clinical use:** Vitamin and nutrient testing identifies deficiencies that can drive fatigue, immune dysfunction, neurological symptoms, and long-term disease risk — and confirms that supplementation is working. ## Who should order it? Anyone with restrictive diets (vegan, low-fat, low-carb), malabsorption conditions, fatigue, hair loss, mood changes, or currently supplementing and wanting to verify dosing. ## Biomarkers measured - Total Glutathione ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $119.99 | $125.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $119.99 | $125.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
