Sounds ok if...: Sounds ok for a typical normal person. Testing for 25-OH-VitD2 and 25-OH-VitD3, and then adding the results to get the total vitamin D level, can help the doctor check the source of the vitamin deficiency and the treatment progress. There is debate over when it would be needed to do these tests. Some doctors feel that giving people more vitamin D would avoid deficiencies and avoid doing lab tests.
