I have a friend who has hashimotos and has been on T4. However, she is loosing hair really really bad and has so little hair left. GP won't do any other test than TSH and T4 and keeps telling her there are no other thyroid medication other than levothyroxine!
She is going to do the total tyroid screen test from Genova Diagnostic to see what her levels are. She is then going to try and see Dr Peatfield with the results. Should she stop her thyroxine prior to testing at all?? I am on T3 and I usually stop taking 24 hours before testing if I am seeing my endo but am just not sure if this is the case with T4 or not??
