What is a Vitamin D Test?
A Vitamin D test is a simple blood test. It measures the amount of Vitamin D in your body. Usually, the test checks for a form called 25-hydroxyvitamin D. This is the best way to see if you have enough Vitamin D. Doctors use this test to find out if you have a deficiency or too much Vitamin D.
