Description

This test is used as a second order test in the assessment of vitamin D status in the body, especially in patients who have kidney disease. If you want a general screening for vitamin D levels, a 25 hydroxy vitamin D level is more appropriate. 1,25 vitamin D is the most active form of vitamin D. It stimulates calcium absorption in the intestine and its production is tightly regulated through concentrations of serum calcium, phosphorus, and the parathyroid hormone
