About this test
Vitamin D1-25 Dihydroxy test measures the active form of vitamin D in blood to help evaluate calcium balance, bone health, and certain kidney disorders.

The Vitamin D1-25 Dihydroxy test measures the level of 1,25-dihydroxyvitamin D, which is the active form of vitamin D in the body. This form of vitamin D plays an important role in maintaining calcium balance, bone health, and proper functioning of the kidneys and parathyroid glands.

Vitamin D helps the body absorb calcium and phosphorus from food. Therefore, maintaining the right level of vitamin D is important for strong bones and overall health. Abnormal levels of active vitamin D may be linked to conditions related to kidney function, bone disorders, or parathyroid gland problems.

Doctors may recommend this test to evaluate certain metabolic conditions or to investigate abnormal calcium levels in the blood. In addition, the test may help in assessing vitamin D metabolism in patients with kidney disease or other related disorders.

Important Instructions:

  • Inform the technician or doctor about any medications you are taking.

  • Mention if you are taking vitamin D supplements or calcium supplements.

  • Inform the technician if you are on kidney or hormone-related medications.

  • Tell the technician if you are taking blood thinners (anticoagulants).

  • Carry previous vitamin D or calcium test reports, if available, for better evaluation.
