This blood test measures Glutathione levels. Glutathione is a tripeptide made of glycine, glutamate and cysteine. Glutathione is the most abundant and important intracellular antioxidant (prevents oxidative damage).


Glutathione is extremely important in excreting xenobiotics (not naturally produced in the body) compounds. Low levels of glutathione have been reported in cardiovascular disease, arthritis, cancer, autism and reduced production of the neurotransmitter dopamine, as well as in debilitating neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Low levels of glutathione are also associated with chronic exposure to toxic elements (mercury, lead, arsenic, cadmium, manganese, iron), chemicals, and some drugs.

Test Preparation For Optimal Results:

If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.

Disclaimer: A health care provider should evaluate a deviation from normal ranges.
