Information on the ZRT At Home Test for Vitamin D3
=view&category=14&partner=VitaminD%20Council 25-hydroxy-vitamin D or 25(OH)D is the circulating form of vitamin D and routinely used to diagnose vitamin D deficiency. The Vitamin D Council recommends 25(OH)D levels be between 50 and 80 ng/mL, year around. These levels assure vitamin D metabolism is normalized. Furthermore, levels of 50-80 ng/mL are “natural” levels, that is, levels normally achieved by people who work in the sun. Low vitamin D levels have been associated with most of the diseases of civilization but only a few controlled trials show vitamin D prevents disease. Controlled trials showing vitamin D treats diseases are even rarer. Many such studies are currently being conducted to see if vitamin D really does prevent or help treat disease. While you wait for the studies to be finished, what 25(OH)D level do you want to have while you wait, a natural 25(OH)D level, one humans had when they worked in the fresh air and sunshine, or a level that is the result of a civilized indoor lifestyle?
DisclaimersCalifornia disclaimers regarding testing do not apply to orders through the Vitamin D Council as the Vitamin D Council is a non-profit organization whose executive president, John Cannell, M.D. will be responsible for ordering testing for 25-hydroxyvitamin D. However, by ordering this test, I agree that I have not entered into a doctor-patient relationship with Dr. Cannell; that is, I understand that Dr. Cannell is not my doctor. I also understand that the vitamin D kit I am buying will report my 25-hydroxy-vitamin D level back to me, but what actions I do or do not take after getting the results back is up to me and my doctor, not Dr. Cannell or the Vitamin D Council.
New York State health law prohibits the testing of specimens collected in or mailed from New York and prohibits the transmission of data from our laboratory to NY physicians or residents. Therefore, we are unable to process such orders at this time.
