Laboratory25-Hydroxyvitamin D3+25-Hydroxyvitamin D2/24,25-dihydroxyvitamin D3+24,25-dihydroxyvitamin D2 ratio panel in Serum or Plasma
Definition
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.
