About this test

Overview of Vitamin C Test

The vitamin C test measures the concentration of ascorbic acid (vitamin C) in the blood. Vitamin C is a vital antioxidant that supports immune function, tissue repair, and overall health.

Functions of Vitamin C

Vitamin C plays a crucial role in:

Supporting the immune system

Promoting skin health and wound healing

Aiding in collagen production

Enhancing iron absorption

Protecting the body against oxidative stress

Health Impact of Deficiency

A deficiency in vitamin C can lead to weakened immunity, fatigue, joint pain, poor wound healing, and in severe cases, scurvy.

Indications for Testing

Frequent infections or lowered immune function

Delayed wound healing or skin problems

Persistent fatigue or general weakness

Bleeding gums or oral health concerns

Suspected scurvy or poor dietary intake

Malabsorption conditions or restrictive diets

What the Test Can Detect

Vitamin C Deficiency: Low levels may indicate a nutritional deficiency that can contribute to various health issues.

Antioxidant Status: Reflects the body's ability to combat oxidative stress and inflammation.

Preparation for the Test

Minimal preparation is needed. Fasting is usually not required, but avoid taking vitamin C supplements for 24 hours prior to testing to ensure accurate results. Always follow any specific instructions provided by your healthcare provider.
