Hello...I've had an underactive thyroid for some fifteen years and now my sister is showing symptoms...as expected her GP tells her it's 'normal'. It looks borderline to me.
June 2014
free T4. 14.7. (9 - 22.7)
TSH. 1.35. (0.35 - 5.5)
June 2015
Free T4 9.9
TSH 1.02. same range.
Be interesting in hearing views, many thanks.
