Vitamin D

The Vitamin D Test (25-Hydroxy) is a blood test that measures the concentration of vitamin D in the body, which is crucial for bone strength, calcium absorption, and immune system function. It helps detect deficiencies that can lead to weak bones, fatigue, and frequent infections. This test is especially important for people with limited sun exposure, dietary restrictions, or medical conditions affecting vitamin D metabolism. Maintaining the right vitamin D level supports overall health and reduces the risk of chronic bone and immune-related issues.
