Hi, I’m due to see the doctor tomorrow, I’ve been told my blood results are as follows-
TSH 0.1 which is the lowest you can have on the scale
T4 4
T3 abnormal
I’m quite worried the usual doctor has retired and he fully understands that I take pure T3 so he’s never had a problem with the TSH and T4 being low.
The lady doctor tells me every time to stop taking t3 because I will have a heart attack!!
Not sure about the abnormal T3?
Well you need an actual figure and the range
Presumably if "abnormal" it's out of range.
If in UK, our doctors have no knowledge about treating people with T3 only. If so, as the blood tests were introduced along with levothyroxine alone - numbers don't correlate.
If taking T3, TSH may well be very low or suppressed. T3 will be high as that's all you take. T4 will be very low as you don't take any and maybe you thyroid gland 'might' produce little or none.
T3 'has' to be abnormal as the tests were for levothyroxine alone, not for liothyronine.
Did you leave 24 hours between your last dose of T3 and the test and take it afterwards.
No, I took the t3 in th morning about 7 and then the blood test about lunch time. X
I think your results may be skewed. Usually the advice is a fasting and as early as possible test with a 24 hour gap between last dose and test. I know some say a 12 hour gap is fine but as I am on T3 I keep to 24hours and take it after test. TSH is highest early a.m. and drops throughout the day.
Gap betweent3 dose and test needs to be 8-12 hrs, ideally as close to 12 as possible. That is the standard advice on this forum from all our real experts. Any less than that and all ft 3 measures is the effective a of absorption, any more than 12 hours and you will have a falsely low result for ft3. 24 hrs advice applies to Levo only.
