Vitamin D
Test
Vitamin D is a vitamin which is used in the regulation of calcium and magnesium absorption from the gut, it is also important for the growth and health of bones. Vitamin D comes from two sources; it can be ingested from foods and supplements or be produced in the skin once it is exposed to sunlight.
Vitamin D tests are used to identify vitamin D deficiency and to monitor diseases that interfere with fat absorption like Crohn’s disease.
This is important to maintain healthy bones, teeth and muscles.
Vitamin D deficiencies can lead to bone diseases such as rickets in children and osteoporosis in adults.
