A vitamin C test measures the amount of vitamin C (ascorbic acid) in your blood. It is usually ordered when a doctor suspects a deficiency or wants to check if you are getting enough of this nutrient.
What it measures
- Vitamin C (ascorbic acid) level — The main measurement; shows how much vitamin C is in your blood at the time of the test.
- Plasma ascorbate — Another term for the same measurement, often used in lab reports.
- Leukocyte vitamin C (rarely) — A less common measure that reflects vitamin C stored in white blood cells, but it is not routinely used.
Who it is for
Doctors typically order this test for people with symptoms of vitamin C deficiency, such as easy bruising, bleeding gums, or poor wound healing, or for those with conditions that affect nutrient absorption.
Preparation
Fasting is not required for a vitamin C test. You can eat and drink normally before the blood draw, but tell your doctor about any vitamin supplements you take.
Results and what they mean
