Vitamin A Blood Test
Vitamin A Blood Test
The Vitamin A Blood Test measures the level of vitamin A in your blood, an essential nutrient vital for vision, immune function, and skin health. Vitamin A plays a critical role in maintaining healthy eyesight, supporting the immune system to fight infections, and promoting cell growth and repair. Studies from institutions like University College London (UCL) and research published in the British Journal of Nutrition emphasise the importance of adequate vitamin A levels, linking deficiencies to night blindness, increased infection risk, and delayed wound healing. Monitoring vitamin A status helps identify deficiencies or excesses, allowing for timely dietary adjustments and supplementation to maintain optimal health.
What Does This Test For?
This test measures the concentration of vitamin A in your blood to evaluate whether you have sufficient levels to support healthy vision, immune function, and skin health. It detects deficiencies that can cause vision problems or immune weakness, as well as excess levels that could lead to toxicity. Understanding your vitamin A status enables you and your healthcare provider to make informed decisions on diet and supplementation to maintain balanced and optimal health.
