    I am yet to find this out, but I know I feel rubbish at 3.6 and 4.8 which were my last two readings. I have been feeling a lot better recently since I cut my carbimazole down, but am not due for bloods for another two weeks.

    I was happy when mine rose from less than 0.001 to 0.70.  Then it went up to 2.7.  Basically I like mine over 1.0 and under 2.0.  I think that is a great range for me.  My last one was 1.01.

    Studies have shown that the concentration of TSH in the serum follows a daily variation (circadian rhythm). In one such study the TSH values of 33 healthy individuals were taken every hour. It was found that TSH shows an average maximum of 2.2mU/l at around 3am and an average minimum of 1.4mU/l at around 3pm. The title of the publication is: "Free Triiodothyronine Has a Distinct Circadian Rhythm That Is Delayed but Parallels Thyrotropin Levels" if you like to read it. 

    Another study has demonstrated that physical activity (for example aerobic exercise) tends to increase the serum concentration of TSH ("Exercise intensity and its effects on thyroid hormones"wink

    Since TSH shows such a large intra-day variation is makes more sense to find a good range instead of an optimum fixed TSH level.

    To compare TSH values it might make sense to schedule the blood test appointments at approximately the same time during the day (since e.g. there is an average difference of 0.4mU/l between the TSH values taken at 9am and 3pm, respectively).

      Yeah I think that test or studies are only true for healthy individuals not me. my thyroid is malfunctioning.  I did try going in same time for every blood test, then going in at different times, but it didnt' make a difference to me.  Now I'm testing how different results would be if I go in on the day I take my methimazole vs on the day meds are off.  so what's your favorite TSH level?
