Vitamin C (with Dilution)

This test measures the level of vitamin C, also known as ascorbic acid, in your blood. It helps show whether you are getting enough of this nutrient to support healthy skin, blood vessels, and immune function. Doctors use these results to check for a deficiency that could explain symptoms like fatigue, easy bruising, or bleeding gums. However, a low result does not identify the specific underlying cause of the deficiency without further medical evaluation.
