Vitamin D (25-OH VitD) test measures the level of vitamin D in your blood. It's crucial for bone health, immune function, and overall well-being. The test specifically measures 25-hydroxyvitamin D, the primary circulating form of vitamin D in the body. This test is important because vitamin D deficiency is common and can lead to various health issues, including osteoporosis, muscle weakness, and increased risk of certain diseases. Factors affecting vitamin D levels include sun exposure, diet, age, and certain medical conditions. Regular testing can help ensure optimal vitamin D levels and guide supplementation if needed.

A high vitamin D level (above 80 ng/mL) is less common but can be harmful. Excess vitamin D can cause:
This is usually due to excessive supplementation rather than natural sources. Treatment involves stopping vitamin D supplements, limiting sun exposure, and reducing vitamin D-rich foods until levels normalize. In severe cases, medical intervention may be necessary.
