Service Description

Vitamin D testing is used to determine whether you have enough vitamin D in your body to support normal bodily functions. An inadequate level of vitamin D is called a deficiency. A more mild lack of vitamin D can be referred to as an insufficiency. Your health care provider may order a vitamin D test in order to: 1. Screen for a possible deficiency or insufficiency if you have a risk factor that increases the likelihood of having a low level of vitamin D. A risk factor is anything that makes it more likely for a health problem to occur. 2. Diagnose a vitamin D deficiency or insufficiency if you have symptoms that suggest low levels. Testing may also be used to diagnose a rare vitamin D toxicity due to excess intake of vitamin D supplements. 3. Monitor your vitamin D levels if you are being treated for a previously detected deficiency.
