Why This Biomarker Matters

Low vitamin C indicates nutritional deficiency affecting immune function and wound healing, guiding dietary changes or supplementation to restore adequate levels.

Understanding Your Results

Normal Range

23 – 85 umol/L

Overview

This test measures ascorbate (vitamin C) levels in blood. Vitamin C is an essential nutrient important for immune function, collagen synthesis, and antioxidant protection. Low levels indicate vitamin C deficiency, which can cause fatigue, poor wound healing, and weakened immunity. Severe deficiency leads to scurvy. This test helps identify nutritional gaps and is sometimes used to assess antioxidant status and guide supplementation in at-risk populations.
