I just found this at-home test for vitamin D deficiency.

I have a couple of initial thoughts about it. At first I was very excited to see it! I guess my enthusiasm was quickly tempered by the skeptic in me. I’ve done some at-home tests before for things like blood sugar and cholesterol and have had conflicting results when compared with regular lab testing. With this particular test, you basically collect a spot of blood on a special piece of paper and then mail it off to the lab for processing. Could this really be as accurate as the mainstream testing? I admit that I don’t know anything about the science behind the testing. The other reason for my hesitancy is that the test costs $112.00, it seems too expensive. I’ve reported that you can now get regular vitamin D testing done by one of our local labs for $70.00. Granted, that doesn’t include the doctors visit fee that most people would have to pay. It just seems to me that for an at-home test to have a good impact, it’s going to have to be substantially less expensive.

I guess the thing to do is to try one of these at-home tests out and compare it to the standard D testing to see how the results match up. If this test is accurate it could be a very cool way for people to do the critical re-checking of their vitamin D levels if their physicians are unwilling to. (You’ll remember that I’ve mentioned that although more doctors are willing to do the initial D testing they often fail to follow-up with re-checking levels to see if the treatment dose is doing the job.)

If anyone out there does one of these please let me know how it goes - ideally you’d have a standard test done at the same time.
