At-home blood tests 2. May 2009 William Davis (6) Our at-home blood tests are proving a hit. So far, vitamin D is the number one most popular test, no surprise. Second--to my surprise--is DHEA. I would have predicted it would have been thyroid testing. Our male and female hormone panels are also proving popular. I've personally been using the thyroid and vitamin D testing to monitor my levels. I increased my Armour thyroid based on a low free T3 value, while my vitamin D was perfect at 77 ng/ml on 8000 units vitamin D3 (cholecalciferol) per day. The process of performing the blood spots is straightforward. The finger pricks are virtually painless using the automatic spring-loaded finger stick devices: The number of blots to make depends on how many tests you'd like. Just a vitamin D test requires 2 blots. If 6 or more tests are ordered at a time, then all 12 blots should be made. (Two spring-loaded lancets are provided in each kit.)

Our own Heart Hawk has posted an editorial on about blood spot testing on Health Central:Simple, affordable home blood testing is a real game-changer in the arena of informed, self-directed healthcare. For the first time broad access to home blood testing, on a scale similar to that enjoyed by persons who routinely test their blood sugar, is available to virtually everyone and it removes doctors as the gatekeepers of these tests. Even private insurance companies and Medicare are beginning to understand the potential for improving healthcare and decreasing costs and are slowly beginning to expand coverage of home blood testing much as they do for diabetics or persons taking anti-coagulants.
