Vitamin A and E

This test measures the amount of Vitamin A and Vitamin E in your blood, which are nutrients essential for vision, immune health, and cell protection. It helps show whether you have a deficiency that could lead to eye or nerve problems, or if you have toxic levels from taking too many supplements. These results help rule out nutritional imbalances as the cause of symptoms like night blindness or muscle weakness. However, this test alone cannot diagnose the specific underlying condition causing the abnormal levels.
