Re: "Normal" Test Results
Your lab results are indeed within the "normal" range. Most savvy doctors who treat thyroid disorders narrow the range of normal for the TSH to .3-2.5, rather than the wider range many labs use. Based on the narrower range, your TSH could be considered on the high side of the normal range. Many of us feel best when our TSH is around "1", yours is a little higher than what "many" people feel good at. Your FT's are also in a normal range. Personally I feel best when my FT's are in the middle of the range similar to yours, but many feel better when the FT's are in the upper third of the range. Your FT4 could be considered slightly low in the range.
More importantly than the lab numbers how do you feel? If you have hypo symptoms with your labs as they are, you may want to try a very small dose of thyroid replacement meds and see if you feel better. To me, your lab numbers aren't at an alarming level. You MAY be slightly hypothyroid, or those MAY just be the "normal" numbers for you since they fall within a very normal range. Hopefully you have a doctor you trust, who will listen to all your symptoms, and treat you based on symptoms as well as lab numbers.
Treating thyroid disorders is a very individual thing. Symptoms are very important in diagnosing a problem, especially when the labs are "normal". The lab numbers for one person to feel well, may be very different for another. There is a poster here, by the log on of Midwest, who explains it like this. The "normal range" for a woman's shoe size is 6-10. If your foot is a size 8, but are wearing a size 6 you will be uncomfortable. Eventhough a size 6 is a "normal" size, you won't be comfortable with it. It's sort of like that with thyroid disorders. It takes some time and trial and error to find just the right place on the "normal" range that you to feel best.
However, just going off my own experiences, don't ignore other medical problems that could be causing symptoms. For instance--fatigue, which is the most common thyroid complaint, can be caused by many things. I have a tendancy to blame any and every symptom on my hypothyroidism, and have to remember there are many other things out there that could be causing me grief.
Best of luck to you, keep us posted to your progress!
