Vitamin C (Ascorbic Acid) in Serum

Why Might You Need This Test?

Your healthcare provider may order this test if you have symptoms of vitamin C deficiency (like fatigue, bruising, or slow wound healing), suspected scurvy, or if you have conditions that affect vitamin absorption (e.g., malabsorption disorders). It may also be done as part of a routine check for nutritional health or before certain treatments.

What to Expect During the Test

A small blood sample is drawn from a vein, usually in your arm. The serum portion of your blood is then analyzed to measure vitamin C levels. This is a quick, painless procedure that typically takes a few minutes.

What the Results Mean

Results help determine if your vitamin C levels are within a healthy range. Low levels may indicate poor diet, malabsorption, or other health issues, while very high levels could suggest supplements or certain medical conditions.

Common Reasons for Testing

This test is often used to diagnose vitamin C deficiency, monitor treatment responses, or check for conditions like scurvy. It can also be part of broader nutritional assessments or before surgeries requiring high vitamin C levels.
