The normal (or natural) range is based on healthy, untreated subjects, not someone taking that specific medication, in which case concentrations would peak about an hour after taking it, and then would gradually decrease through the day or night until the next dose. On the other hand, if you had been taking the supplement regularly for awhile and the blood test was done right before taking a dose, then his note might have meant that he expected it to be low, but was surprised to see that it wasn't. Be sure to ask him what he meant. All we can do is guess. The elevation of TSH is a function of both reduced levels of various thyroid hormones and the TIME those hormones have been missing. TSH keeps creeping up the longer the condition persists without the desired response. That is why TSH level is not proportional to how badly you feel. It is more like a complicated product of degree of illness and the time you have felt that way. One part of this is that T3 and the other hormones that affect TSH can only go so low. Concentration cannot go negative. So, the pituitary responds to a drop with a little TSH. If that doesn't work, it tries a little harder, and so on. Consequently, a TSH of 8 can be associated with symptoms just as bad as those with a TSH of 32. The 32 just indicates longer suffering. The tricky part in using TSH for titration is finding where the crossover to feeling well again is. For some, a TSH of 1.0 may be fine. For others, 0.1 is still too high. I start feeling pretty miserable above 3.0. Chuck Quote Link to comment Share on other sites More sharing options...
