VIT C, SERUM/HEPARIN PLASMA

Vitamin C, Serum/Heparin Plasma

What it is

The Vitamin C, Serum/Heparin Plasma test measures the concentration of Vitamin C (ascorbic acid) in the blood. Vitamin C is a water-soluble vitamin and a powerful antioxidant that supports immune function, collagen synthesis, wound healing, and absorption of iron. Measuring its levels helps identify nutritional deficiencies or excess intake.

Uses

This test is used to diagnose Vitamin C deficiency (scurvy), evaluate nutritional status, monitor patients receiving Vitamin C supplementation, and assess patients with malabsorption disorders or chronic illnesses that may lower vitamin levels.

Symptoms That May Lead to the Test

Doctors may recommend this test if you experience frequent infections, fatigue, slow wound healing, bleeding gums, joint pain, easy bruising, or anemia. It is also used in patients with poor dietary intake, alcoholism, or gastrointestinal disorders affecting nutrient absorption.

Abnormal Results

Low Vitamin C: Suggests deficiency, which may lead to scurvy. Common in cases of poor diet, malabsorption syndromes, alcoholism, chronic kidney disease, or smoking (which increases Vitamin C requirement).

High Vitamin C: Usually due to excessive supplementation. Very high levels may cause gastrointestinal upset, kidney stones, or interfere with certain lab tests.

Risks

This test requires a standard blood sample. Risks are minimal and limited to mild pain, bruising, or bleeding at the puncture site, with rare chances of dizziness or infection.
