Vitamin D Test
About Vitamin D Test
The vitamin D test, also known as the 25-hydroxyvitamin D test or 25(OH)D test, is the most accurate way to measure the level of vitamin D in your blood. Vitamin D is both a vital nutrient that comes from food and a hormone that your body produces when your skin is exposed to sunlight. It is essential for bone strength, muscle health, immunity, and overall well-being.
A vitamin D test is commonly used by doctors to check if you have vitamin D deficiency, insufficiency, or even excess levels that may cause vitamin D toxicity. People with low levels of vitamin D are more likely to develop weak bones, osteoporosis, fractures, and muscle weakness. On the other hand, excess vitamin D levels can cause hypercalcemia, kidney stones, or organ problems.

Functions of Vitamin D
The vitamin D test helps identify whether your body has sufficient vitamin D for critical physiological functions. Vitamin D plays a vital role in:
- Bone health: It promotes calcium absorption and bone mineralization, preventing rickets in children and osteoporosis in adults.
- Immune system regulation: Adequate vitamin D levels boost your immune defense against infections.
- Muscle health: It supports muscle strength and prevents cramps or weakness.
- Heart function: Vitamin D helps regulate blood pressure and cardiovascular function.
- Cell growth: It maintains healthy cellular growth and reduces inflammation.
- Cancer prevention: Adequate levels may reduce the risk of certain cancers.
- Hormonal balance: Vitamin D regulates normal blood calcium and phosphorus levels.
By checking your levels with a vitamin D test or 25-hydroxyvitamin D test, doctors can identify deficiencies early and recommend corrective measures. You can book vitamin D test online and verify the vitamin D test price before booking.
