Ascorbic Acid (Vitamin C), Blood Test
Summary
The Ascorbic Acid (Vitamin C) blood test measures the level of Vitamin C in your bloodstream. This vitamin is essential for several bodily functions, including the repair of tissues and the enzymatic production of certain neurotransmitters.
Purpose
The procedure is designed to diagnose Vitamin C deficiency, which can lead to conditions such as scurvy. The test helps in ensuring proper vitamin levels for overall health and is used to evaluate dietary insufficiencies or malabsorption issues.
Indications
- Symptoms of Vitamin C deficiency such as fatigue, muscle weakness, joint and muscle aches, bleeding gums, and skin rashes.
- Patients with conditions that might affect nutrient absorption like Crohn’s disease or celiac disease.
- Individuals with poor dietary intake or those at risk for malnutrition.
Preparation
- Fasting is typically required for several hours before the test.
- You may need to avoid certain medications and supplements prior to the test, as instructed by your doctor.
- Inform your healthcare provider of all medications, supplements, and herbs you are taking.
Procedure Description
- A healthcare professional will clean the skin where blood will be drawn.
- A tourniquet will be applied to your upper arm to fill the veins with blood.
- A needle is inserted into the vein, usually in the arm, and blood is drawn into a vial or syringe.
- The sample is labeled and sent to the lab for analysis.
Tools and equipment include antiseptic wipes, a tourniquet, needles, vials, and syringes. Anesthesia or sedation is not applicable for this procedure as it is a simple blood draw.
