Thank you so much. Just checked the site and the TSH only is $40.
No, it's not a scam. Online testing is usually reasonably priced and very prompt (sometimes faster than going to your local lab). I know some members have been impressed with healthcheckusa. While your at it, consider having free T3 and free T4 tested as well. This will give you a much more complete profile than TSH alone. My hypo was actually diagnosed via online lab work, but I believe the lab I used (several years ago) has either changed their name or is no longer in business. The TSH test cost me around $35 and was verified a couple of weeks later by local lab work.
