# 25-Hydroxy Vitamin D (D2+D3 Fractionated), LC/MS-MS

> This test measures the total amount of vitamin D in your blood by combining the levels of two specific forms, vitamin D2 and vitamin D3. It helps show whether your body has enough vitamin D to maintain strong bones and absorb calcium effectively. Doctors use this result to identify a vitamin deficiency that might cause fatigue or bone weakness. However, this test cannot determine the specific cause of a deficiency or diagnose bone diseases like osteoporosis on its own.
