What is a Vitamin A Test in Visit Clinic?
The Vitamin A test measures the amount of vitamin A (usually serum retinol) in your blood. Vitamin A is important for healthy vision, immune function, growth, and healthy skin and mucous membranes. Low levels can cause night blindness, dry eyes, and higher infection risk. High levels can cause nausea, headache, and liver problems. Doctors use this test to check for deficiency in at-risk people, to monitor treatment or supplements, and to investigate malabsorption or liver disease that affects vitamin storage. It helps guide nutrition advice and safe supplement dosing. Results are combined with symptoms and other tests to make clinical decisions.

Why Take a Vitamin A Test in Visit Clinic?
Vitamin A is often ordered alone or as part of a nutrition or micronutrient panel to assess vitamin stores. Doctors may request it when someone has poor night vision, dry eyes, frequent infections, poor growth, or signs of liver disease. It helps diagnose deficiency or toxicity. Abnormal results can come from poor diet, malabsorption, liver disorders, or excessive supplement use. A family history of metabolic or liver disease may increase the need for testing.
