Vitamin D3 (25 Hydroxy Cholecalciferol)

The Vitamin D3 (25 Hydroxy Cholecalciferol) test is a diagnostic tool used to measure the concentration of 25-hydroxyvitamin D in the blood. Vitamin D is a fat-soluble vitamin that plays a crucial role in calcium and phosphorus metabolism, thereby influencing bone health, muscle function, immune system regulation, and various physiological processes. 25-hydroxyvitamin D is the major circulating form of vitamin D and is considered the most reliable indicator of an individual’s vitamin D status. Insufficient levels of vitamin D have been associated with various health conditions, including rickets, osteomalacia, osteoporosis, autoimmune diseases, cardiovascular diseases, and certain cancers. Conversely, optimal vitamin D levels have been linked to improved bone health, reduced risk of falls and fractures, enhanced immune function, and better overall health outcomes.
