The Vitamin D Blood Spot profile measures vitamins D2, D3 and total Vitamin D to give an accurate and comprehensive assessment of vitamin D status.

25-Hydroxyvitamin D is important for bone health and calcium absorption, immune function and also plays a role in neurodegenerative and cardiovascular issues, and other conditions. 

Vitamin D occurs in two forms:
- D3 is obtained through sun exposure and from animal diet sources 
- D2 is obtained through vegetable diet sources. 
Both forms can be used to fortify various foods and in supplements
