I wondered if anyone could advise me. In was diagnosed 6 weeks ago with underactive thyroid with a tsh reading of 181. I was advised a normal reading would be 5 so this is extremely high. They medicated 75mg Euthyrox and asked me to come back in 6 weeks to be retested. My result have come back normal despite me feeling very unwell some days and weak. Could the fact that I took my medication 2 hours before bloods give an inaccurate result? Any guidance would be appreciated.
