5 month old has high tsh but normal ft4
My five month old got his tsh tests done and his tsh is 6.4 and his ft4 is 1.2. The doctor said that his tsh is lower than before (it was higher than 6.4 before. I don’t have the exact number) but the doctor has said that gets gotten lower so he suggests to do another test in a few weeks or so to see if it gets to normal range. I’m so worried Cuz I’ve heard hypothyroidism in infants can delay development, and I don’t really want that.
