Immunochemiluminometric assay (ICMA). This assay is performed on the DiaSorin LIAISON® instrument in multiple laboratories throughout LabCorp. This highly automated test measures both D2 and D3 together and reports a total 25-hydroxy vitamin D. Major clinical studies, including (but not limited to) the Centers for Disease Control (CDC) National Health and Nutrition Examination Survey (NHANES) data base, the Women's Health Initiative (WHI) Studies, and the Harvard-Based Health Professionals Studies, employed DiaSorin reagents.

Vitamin D, 25-Hydroxy (25-OH vitamin D) is the major circulating form of vitamin D and the best indicator of overall vitamin D status. This test measures 25-OH vitamin D levels in the blood to evaluate vitamin D sufficiency and diagnose deficiency. Vitamin D is essential for calcium absorption, bone health, and numerous other physiological processes. The 25-OH form is produced in the liver from dietary vitamin D and sun exposure, and serves as the storage form that can be converted to the active 1,25-dihydroxy form as needed. Deficiency can cause rickets in children, osteomalacia in adults, and contribute to osteoporosis. Low levels are also associated with increased risk of certain cancers, autoimmune diseases, and cardiovascular conditions. This test is essential for evaluating patients with bone disorders, monitoring vitamin D supplementation, and assessing nutritional status in various populations.
