25-Hydroxyvitamin D3+25-Hydroxyvitamin D2/24,25-dihydroxyvitamin D3+24,25-dihydroxyvitamin D2 ratio panel in Serum or Plasma
Active
Term Description
Testing for an elevated ratio of 25HDN to 24,25 DHD can be used to reveal the likely presence of mutations in the CYP24A1 gene. CYP24A1 converts 25 hydroxyvitamin D to 24,25 dihydroxyvitamin D, a process thought to prevent overproduction of the active metabolite 1,25 dihydroxyvitamin D.

Part Descriptions
LP182450-9 Calcidiol+ercalcidiol
The total of 25-hydroxyvitamin D3 (calcidiol) + 25-hydroxyvitamin D2 (ercalcidiol), which is often reported simply as 25-hydroxyvitamin D, or 25-OH-D.

LP417249-2 Calcidiol+ercalcidiol/24r-Hydroxycalcidiol+24r-Hydroxyercalcidiol ratio panel
24,25-dihydroxyvitamin D (24,25 DHD), also known as 24r-Hydroxycalcidiol, is an INactive metabolite produced by alternative hydroxylation of 25 hydroxyvitamin D (25HDN) by the CYP24A1 enzyme. The hydroxylation by CYP24A1 competes with hydroxylation to active form 1,25-dihydroxyvitamin D (1,25 DHD) by the CYP27B1 enzyme, and is an important process that prevents overproduction of 1,25 DHD and resulting vitamin D toxicity. Testing for an elevated ratio of 25HDN to 24,25 DHD can be used to reveal the likely presence of mutations in the CYP24A1 gene PMID: 22648296.
