So, what have we done to mitigate the problem of inappropriate 1,25-Dihydroxyvitamin D orders? As for all our tests, we have defined the testing indications in our electronic and paper test ordering catalogs in the “Useful For” field. Comparing the “Useful For statements you see that 25-Hydroxyvitamin D is indicated for the “Diagnosis of vitamin D deficiency,” whereas 1,25-Dihydroxyvitamin D is indicated as a second-order test in the assessment of vitamin D status, especially in patients with renal disease.  We have also produced a Hot Topic on vitamin D testing, which is accessible on our website, I encourage you to check out this video.
