Vitamin D Assays
Vitamin D is a fat-soluble hormone involved in the intestinal absorption and regulation of calcium. It plays a vital role in the formation and maintenance of strong, healthy bones. Insufficient vitamin D levels have long been associated with rickets in children and osteomalacia in adults, and long-term insufficient vitamin D calcium absorption leads to osteoporosis. However, in recent years, the vitamin D immunoassay has become known as an indicator of general health status, and there have been multiple publications linking low vitamin D test scores to several disease states, such as cancer, cardiovascular, diabetes, and autoimmune diseases.1
The Siemens Healthineers calcium vitamin D testing portfolio enables medical professionals to evaluate total amount of 25-hydroxy-vitamin D (both D2 and D3) in the blood. This ensures patients have the most accurate result regardless of level and whether or not they are supplemented over-the-counter or by prescription.
