# Vitamin A

> This test measures the amount of Vitamin A in your blood, a nutrient essential for healthy vision and immune function. It helps show whether your levels are dangerously high from supplements or too low due to poor nutrition or absorption issues. Doctors use this result to evaluate symptoms like night blindness or skin problems and to rule out vitamin toxicity. However, a single test result cannot diagnose the specific underlying cause of an abnormal level without further medical evaluation.
