Vitamin D Blood Test

Vitamin D Blood Test

A Vitamin D Blood Test is a simple diagnostic test that measures the level of vitamin D in the blood, primarily in the form of 25-hydroxyvitamin D. This vitamin plays a crucial role in maintaining healthy bones and teeth, supporting immune function, and regulating calcium and phosphorus levels in the body. A deficiency in vitamin D can lead to conditions such as bone weakness, fatigue, muscle pain, and in severe cases, rickets in children or osteomalacia in adults.

The test is often recommended for individuals at risk of deficiency, including those with limited sun exposure, darker skin tones, older adults, or people with certain medical conditions affecting nutrient absorption. Based on the results, healthcare providers can determine whether supplementation or lifestyle changes are needed to restore optimal vitamin D levels. Monitoring vitamin D through blood testing helps ensure proper bone health and immune support, contributing to overall wellness and disease prevention.
