30 and 74 ng/mL: Doctor may order a vitamin d test alone, or include the test with other blood tests. Your blood sample is tested using a test called 25-hydroxyvitamin d. Your doctor may also order the 1, 25-dihydoxyvitamin d test. You should not eat for four hours prior to testing. A normal range of vitamin d in your blood from the 25-hydroxyvitamin d test is between 30 and 74 ng/ml, or nanograms per milliliter.
