What does the Total Antioxidant Function test measure?

Q: What is the reference range for Total Antioxidant Function?

The standard reference range for Total Antioxidant Function is Reported as a composite score reflecting intracellular antioxidant capacity; reference range and interpretation are SpectraCell proprietary.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Total Antioxidant Function (TAF) is a clinical biomarker used in genetic-testing assessment. The total antioxidant function score integrates the sufficiency of multiple antioxidant nutrients and enzyme systems (glutathione, vitamins C and E, alpha-lipoic acid, coenzyme Q10, selenium) measured functionally in lymphocytes. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Reported as a composite score reflecting intracellular antioxidant capacity; reference range and interpretation are SpectraCell proprietary.
Units: Functional score
Measured In: 1 test

What is Total Antioxidant Function?

The total antioxidant function score integrates the sufficiency of multiple antioxidant nutrients and enzyme systems (glutathione, vitamins C and E, alpha-lipoic acid, coenzyme Q10, selenium) measured functionally in lymphocytes. It reflects the cell's capacity to buffer oxidative stress rather than a single molecule's serum concentration.

Why is Total Antioxidant Function measured?

A reduced antioxidant function score may signal heightened oxidative stress or marginal nutrient status in conditions such as chronic inflammation, cardiovascular disease, diabetes, or neurodegenerative disorders. It complements individual micronutrient results by providing a systems-level view of redox balance.
