I live in Spain and got tested in March and (of course!) was told everything was fine. I'm thinking of jiggling my T3/T4 about and have just noticed another line on the test results I didn't notice before. All of the first numbers of the actual results are in bold except the one marked " "
T3 Total 1.02 0.59-2.00
underneath this just in normal print is
"1.58" 0.91 -3.10 (this is the bit I missed)
Free T4 1.20 0.80-1.80
TSH 0.07 0.23-5.50
Can anyone tell me what the second line represents please?
