VITAMIN D 1,25 – DIHYDROXY

The vitamin D 1,25-dihydroxy test measures the level of 1,25-dihydroxyvitamin D, the active form of vitamin D, in the blood. This test is used to diagnose and monitor conditions affecting vitamin D metabolism, such as vitamin D deficiency, hyperparathyroidism, and chronic kidney disease. Elevated 1,25-dihydroxyvitamin D levels can indicate conditions such as sarcoidosis or lymphoma, while low levels suggest vitamin D deficiency or impaired renal function. The 1,25-dihydroxyvitamin D test provides valuable information for assessing vitamin D status, diagnosing underlying conditions, and guiding treatment decisions to manage vitamin D levels effectively.
