Vitamin D
The Vitamin D Test measures 25-hydroxy Vitamin D levels in blood to assess bone strength, immunity, and overall health.About Test
The Vitamin D Test measures the level of Vitamin D in your blood, which is essential for maintaining strong bones, healthy muscles, and a well-functioning immune system.
Vitamin D is primarily produced in the skin when exposed to sunlight. It can also be obtained from foods like fortified dairy products, mushrooms, and fatty fish. However, despite these sources, Vitamin D deficiency is very common due to modern indoor lifestyles and limited sun exposure.
This test evaluates the level of 25-hydroxy Vitamin D (25(OH)D), which is the most accurate indicator of your body’s Vitamin D status. Abnormal levels may indicate deficiency or excess, both of which can affect overall health.
A Vitamin D Test helps in diagnosing deficiency, monitoring treatment, and preventing complications related to bone and metabolic health.
