The IDS-iSYS 1,25-Dihydroxy Vitamin D assayis a complete assay system intended for the purification of 1,25-dihydroxyvitamin D [1,25D] in human serum or plasma by immunopurification followed by quantitative determination on the IDS-iSYS Multi-Discipline Automated System to assess 1,25-dihydroxyvitamin D deficiency associated with renal disease.

1,25-dihydroxyvitamin D (1,25(OH)2D) is the biologically active metabolite of vitamin D that plays a key role in the regulation of calcium and phosphate homeostasis. Measurement of 1,25(OH)2D is important in managing patients with renal failure, hyperphosphataemia, hypomagnesaemia, hypoparathyroidism, pseudohyperparathyroidism, vitamin D dependent rickets, granulomatous disease, lymphoma, primary hyperparathyroidism and hypercalcaemia.
