What's the best gap to leave after taking T3 before pricking finger? I have twice previously left 12 hours after T3 and 24 hrs after T4 by delaying my morning meds until after pricking and T3 levels have been 5ish mcg. This time, because I have altered my times of medication, I took my T4 and T3 at 4am, then T3 at 10am then a gap of 12 hrs and did finger prick at 10pm. This has shown my T3 to be just over range and T4 higher in range than before. For T4 this is probably because it was only 18hrs after medicating. I was only looking at my T3 level so I'm not bothered with the T4 result.
About 6 weeks ago I managed to obtain my T3 from the GP but I had a third of a foil left of my Turkish T3 left which I decided to use first. I was then taking a total of 18.75mcg T3 with 75mcg T4. (I still had a few aches and pains, but nothing to write home about). Because the mp T3 is such a small tablet to cut up I decided to raise my Turkish T3 to 25mcg then swap tablet for tablet. Some people have felt that Turkish T3 is weaker so this fits in with that thought. When I used up the foil I switched to mp T3. This is when I finger pricked.
FT4 16.83 (12-22)
FT3 7.23 (3.1-6.8)
TSH 0.005 (.27-4.2)
FT3 will now fall because I will only be medicating 20mcg so I don't think there's anything to worry about but next time in a month when shall I do the finger prick? I take my meds at 4am (10mcg), 10am (5mcg) and 4pm (5mcg) with T4 at 4am. When I saw the T3 result I thought it was high having raised from 5.6 to 7.23 for a raise in med from 18.75 to 25mcg. (Still got aches but in my back now not thighs)
Best wishes everyone
