TRD year done?

Christie

Hi has anyone ever had a TRH blood test done? I’ve had my thyroids checked before but they always came back normal but I recently read about a better test called TRD. I had two miscarriages in 4 months and am wondering if it’s my thyroids, ever since havng my son 4 years ago my hair still falls out about as much as right after I had him. If anyone knows anything about this test please let me know
