Following some discussion about timing of TFTs I'm posting results taken at 2 different hospitals and 2.5 hours apart last week. Both tests were fasting because of cholesterol morning draw:
11.00 TSH 0.17 (0.35-5.5) FT4 17.2 (10.0-22.7)
13.30 TSH 0.13 (unknown) FT4 18.3 (9.0-19.0)
I intended my 2nd test to be drawn at 13.00 when TSH is lowest as GP had agreed to reduce my T4 without endo's consent and I didn't want him to get a row.
