Vitamin D (25 OH Cholecalciferol) Blood Test
The VITAMIN D (25 OH Cholecalciferol) test measures the level of 25-hydroxyvitamin D in the blood. This is the main form of vitamin D circulating in the body and is considered the best indicator of overall vitamin D status.
Vitamin D plays an important role in helping the body absorb calcium and phosphorus, which are essential for maintaining strong bones and teeth. It also supports muscle function, immune health, and overall well-being.
Low levels of vitamin D may lead to problems such as bone weakness, muscle pain, fatigue, and increased risk of fractures. In children, severe deficiency may cause rickets, while in adults it may lead to osteomalacia or osteoporosis.
