Understanding your vitamin deficiency blood tests
These tests look at essential vitamins and minerals that support your energy, blood formation, and bone health. Doctors often check vitamin B12, vitamin D, folate, and iron together because their roles in the body closely connect. Reviewing them as a group gives your healthcare team a complete picture of your nutritional foundation.

Frequently asked questions
- Why are vitamin B12, vitamin D, and iron tested together?
