Vitamin D Tests. One of the more common vitamin and mineral blood tests is the vitamin D test. A vitamin D deficiency or excess can lead to problems such as bone malformation, bone weakness and improper calcium metabolism.
The Vitamin D Test measures the Total, D2 and D3 blood levels of Vitamin D, 25-Hydroxy (also known as Vitamin D, 25-OH). A Vitamin D test is a great measure of a body's Vitamin D status. Adequate Vitamin D is important for maintaining healthy bone and muscles and the immune system.
