Three commercially available kits for 1,25-dihydroxyvitamin D [1,25(OH)2D] determination were compared with a liquid-chromatographic method. Serum samples were analyzed for 1,25(OH)2D from 70 healthy subjects (age 2.2-17.5 years; 35 males, 35 females), some (n = 5) given orally high vitamin D3 doses. In addition, 1,25(OH)2D was measured in 28 patients with untreated diseases associated with low (n = 16) or high (n = 12) serum concentrations of the hormone. The results showed that the commercial kits were sufficiently accurate with respect to the comparison method and suitable for routine clinical work.
