Vitamin D, 25 - Hydroxy (NHC)

The Vitamin D, 25-Hydroxy test measures the level of 25-hydroxy vitamin D [25(OH)D], the primary storage and circulating form of vitamin D in the body. It is the most reliable test for assessing vitamin D status and helps evaluate bone health, calcium absorption, and overall mineral metabolism. This test measures both Vitamin D2 and Vitamin D3 components, providing a comprehensive assessment of vitamin D levels. Vitamin D deficiency is common, particularly in older adults, and may lead to osteoporosis, secondary hyperparathyroidism, rickets in children, and osteomalacia in adults, while excessive vitamin D levels may indicate hypervitaminosis D.
The Vitamin D, 25-Hydroxy test is recommended for individuals with bone pain, muscle weakness, recurrent fractures, osteoporosis, limited sun exposure, malabsorption disorders, or suspected vitamin D deficiency. It is also used to investigate the causes of rickets and osteomalacia, monitor vitamin D replacement therapy, and assess overall bone and metabolic health. At Nidan Pathology Lab, we provide NABL-accredited testing, FREE home sample collection, advanced laboratory technology, and accurate, timely reports to support the diagnosis and effective management of vitamin D-related disorders.
