I had a blood test a couple of months ago but TSH is fine, around 1. I am not at home so cannot give accurate result.
My dose has been stable for sometime now.
As long as I feel well I wont bother having a test at all. GP might insist on a yearly one.
If doctors adjust doses according to the TSH the patient might well never recover as a lot of members have been on a treadmill with dose up/down according to the TSH. I think if you have a high T3 you might feel overstimulated and reduce it yourself. However, this is an excerpt and don't know if it answers for you:-
Dr. Lowe: With most patients, I use thyroid function tests (TSH, free T3, and free T4) and thyroid antibodies only for a patient’s initial diagnosis. Afterward, I follow the practice, in principal, of Dr. Broda Barnes—that is, measuring tissue effects of particular dosages of thyroid hormone rather than remeasuring TSH, free T3, and free T4 levels.
My reason for this different protocol is simple: the TSH, free T3, and free T4 tell us only how the pituitary and thyroid glands are interacting. Of course, the test levels may also tell us something of the influence of thyroid hormone over the hypothalamus in its secretion of TRH, another hormone that influences the pituitary gland's secretion of TSH.
Tissue measures of thyroid hormone tell us what is most important, that is, how the patient's tissues other than the pituitary and hypothalamus are responding to a particular dosage of thyroid hormone.
Also from the above::
TSH levels don’t significantly correlate day-to-day or week-to-week. One research group measured the TSH and free T3 and free T4 levels of ten normal young men. When they measured the levels every 30 minutes for 24 hours, they found that the hormone levels were lower during the day and higher at night. During the day, the free T3 was 15% lower, the free T4 was 7% lower, and the TSH was 140% lower. When the researchers measured the hormone levels every five minutes for six to seven hours (7 PM-to-11 PM), the levels varied every thirty minutes. The TSH level varied 13%, the free T3 15%, and the free T4 11%.
