Glutathione testing is still not a mainstream procedure like cholesterol testing or blood sugar testing, although glutathione’s role in health and disease has been studied extensively, and persistently low glutathione is associated with increased mortality.
One of the reasons is that glutathione levels fluctuate throughout the day (the lowest being in the early morning) in response to exposure to toxins, pathogens, smoke or car exhaust fumes, medications, food choices, stress levels, illness, etc. – thus, repeated testing may be required.
Another reason is that glutathione is an integral part of your body’s own antioxidant system and other parameters should be considered along with glutathione levels – evaluation of a person’s antioxidant reserves, the activity of protective antioxidant enzymes and the degree of cellular damage from oxidative stress if any.
Ray had glutathione testing done back in 2006 and then again in 2007. Our family physician was open–minded enough to suggest and order an Oxidative Stress Analysis kit from Genova Diagnostics, a NC based laboratory which is one of very few that provide this type of testing. The last time I checked (2013) such well-known and widely used laboratories as Quest Diagnostics and LabCorp do not provide oxidative stress evaluations.
Ray had already been on Immunocal and glutathione boosting protocol and diet for good 6 months prior to this testing (for details see our Peripheral Neuropathy page). All his results came back within normal range both times.
If you would like to get your glutathione levels and/or oxidative stress status evaluated I recommend you do it before and after you start raising your glutathione. This way you will be able to compare the before and after results and see how effective your glutathione boosting protocol is.
Oxidative Stress Analysis 2.0 (blood) from Genova Diagnostics evaluates the following:
|Antioxidant Reserves||Normal Reading|
|Glutathione (GSH)||>= 669 micromol/L|
|Total Antioxidant Capacity (TAC)||>= 0.54 mmol/L|
|Antioxidant Enzymes||Normal Reading|
|Superoxide dismutase (SOD)||5,275-16,662 U/g Hb|
|Glutathione peroxidase (GPx)||20.0-38.0 U/g Hb|
|Cellular Damage||Normal Reading|
|Lipid peroxidation||<=10.0 micromol/L|
To get you glutathione and/or oxidative stress levels tested you will need to do the following:
