What this test is

This blood test quantifies the concentration of vitamin C, also known as ascorbic acid, in your bloodstream. It is used to assess vitamin C status and can help identify a deficiency. The test is not a routine screening tool for most healthy individuals.

What it measures

  • Vitamin C (ascorbic acid) — reflects the amount of vitamin C circulating in the blood

What the test involves

The test requires a standard blood draw, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test if you have symptoms that could suggest a vitamin C deficiency, such as easy bruising, bleeding gums, or poor wound healing. It may also be ordered for individuals with limited dietary intake or certain medical conditions that affect nutrient absorption.

Preparation

How results are reported

Results are reported as a numerical value that indicates your vitamin C level. Reference ranges can differ between laboratories, so your result should be interpreted in the context of the range provided by the testing lab.
