90/60 mmHg according to what a doctor told me during a measurement a month ago (though my journal says 98/60 for some reason). 105/60 in an another measurement a week before that.
Thyroid panel:
P-TSH mIE/L 1.5 (0.3-4.2)
P-T4, free pmol/L 15 (12-22)
P-T3, free pmol/L 5.2 (3.1-6.8)
S-Ak, (IgG) TPO kIE/L 8 (<34)
The last one is TPO antibodies. The parentheses are the reference ranges at my lab.
All values are within what is considered normal range. I've also had the thyroid physically examined (though palpation) and it appears there are no abnormalities (it's not swollen or enlarged).
I have not measured my body temperature.
Your systolic is low, but I'm sure you're well aware of that.
The thyroid panel looks normal, but there exists a bunch of people (including a few doctors one of whom, I believe, wrote a book) who think that hypothyroidism is seriously underdiagnosed and that it will not necessary show up in the TSH/T3/T4 tests. Google it up. I have no opinion on their claims.
There is also, of course, the non-answer that your thermoregulation set point just happens to be very low :-/
