A total glutathione test measures the amount of glutathione in your blood. Glutathione is an antioxidant made by your body that helps protect cells from damage. It is ordered mainly in wellness or research settings to look at oxidative stress, not to diagnose a specific disease.

What it measures

  • Total glutathione — The combined amount of reduced and oxidized glutathione in your sample.
  • Reduced glutathione (GSH) — The active form that neutralizes harmful molecules called free radicals.
  • Oxidized glutathione (GSSG) — The used-up form, created after glutathione does its antioxidant work.
  • GSH/GSSG ratio — A calculated comparison that can suggest how much oxidative stress is present.

Who it is for

This test is usually ordered by a clinician or researcher exploring antioxidant status, oxidative stress, or general wellness. It is not a routine screening test.

Preparation

No fasting is usually required. Tell the person drawing your blood about any supplements, especially glutathione or N-acetylcysteine, since they can affect results.

Results and what they mean

Results are reported as a concentration in your blood, often with a reference range from the testing lab. Your clinician interprets the number alongside your history, symptoms, and other tests. This is general information, not medical advice; talk with a qualified clinician about your results.

Requesting the Total Glutathione Test in Texas

Order online, choose a certified collection site in Texas, and review results through a secure portal. No referral is required, and orders are processed confidentially. Access across South is expanding, so confirming a site ahead of time is worthwhile.

Frequently asked questions

Do I need to fast?

Typically no. Follow any instructions your ordering clinician gives you.

Can food or supplements change my level?

Yes. Diet and supplements such as glutathione or N-acetylcysteine may affect results, so report them before testing.

Is a low result a diagnosis?

No. A low value is a lab finding, not a diagnosis. Only a clinician can interpret it in context.

How soon will I get results?

Turnaround is usually 1 to 3 business days after the sample reaches the lab.
