How to get your reverse T3 tested

Order reverse T3 (reverse tri-iodothyronine) blood testing online

In the majority of US states you can order reverse T3 testing online and have the blood drawn at a local blood draw center (see my general overview of the process).

I'd suggest ordering from Life Extension because they have the cheapest price I know of ($55), and I've been happy with their service. You can also compare the other 5 reverse T3 test providers I've found.

Take a look at my state-specific issues page if you're in AZ, MD, NJ, NY or RI.

Understanding the results

The American Association for Clinical Chemistry has basic summary of reverse T3.

A site called Stop The Thyroid Madness has some opinions on levels and ratios and suggestions for influencing them.

Please leave a comment if you see a way to improve this page or if you have any questions. Keep in mind that I know little about the medical side of bloodwork, I just enjoy making sites with lists of things.
