Hi, I hope somebody may be able to offer advice.
My doctor tested my thyroid again last week, results are in but I am a little confused. This time I did the test on a fast and did not consume my thyroxin (5o microg).I wasn't tested for T3 even though I asked and the doctor who indicated he would approve my request.
Results indicate Free T4 12.7
TSH 3.5 ( which has risen significantly by my fasting Levothyroxin for the blood test). My Previous result in October without the fast showed TSH 1.4
( as an aside) I found my test results dating back to March 2002 ( I was not diagnosed with HypoThyroid till 2010) My results from 2002 are TSH - thyroid stim. hormone 1.860 T4 (Thyroxine) 14.700 I noticed the notes for T4 provide guidance " Normal = 50 - 151 nnmol. "My result of 14.7 ( in 2002) indicates abnormal T4 but this was never addressed at the time?
In summary I am trying to understand what my body is telling me with a rise from TSH 1.4 to TSH 3.5 when abstaining from Levothyroxin for the blood test? Golly I am so confused. Thanks for reading my post
