Re: Why test TSH, Free T3 & T4, antibodies?
I too had RAI ( in 2002) and am working on getting my labs straight.
One thing I noticed about your labs is that your doctor is trying to keep your TSH low (which is a good thing as most people feel good when their TSH is at or around 1). A lot of doctors get their patients TSH under 5 or 3 and call it good. Also, your doctor is already testing your Free T4 right? In looking at your labs, it looks like your doctor has kept you at borderline hyper for the last couple of years. Getting your Free T3 tested would give a much broader picture of where your thyroid is at. If, for instance, your Free T3 #'s high and out of range, it would indicate a hyper status. If, however, your T3 is low, but still in range it might indicate you need T3 (in the form of Cytomel) added to your synthetic T4 (or Armour - which has both T4 & T3). Some people's labs can look ok by looking at the Free T4 & TSH, but then look terrible when you see the Free T3 (some of the synthetic T4 you take is supposed to convert automatically into T3, but this doesn't always happen with people and they end up with good TSH & T4 labs, but crappy T3 labs). Anyhow, I've kind of jumped all over the place, but I was trying to give you some real life examples of why it's good to get your Free T3 tested.
Also, if your doctor gives you a hard time, just tell you you want to make sure your T4 is being converted to T3 because that's something that ya'll have never looked at. If she still doesn't want to, just laugh and ask her to humor you. I recently started seeing a new doctor and he did request labs on my antibodies, however I'm not sure why. I mean, you could go ahead and get yours tested for giggles and again, just tell your doctor to humor you.
