Hello, my 40 days old daughter was recommended a tsh , ft3 , ft4 test by a doctor. my baby is normal and has no sort of problems as such. is?

Confusing question: Actually you did not ask a clear question.The tests you mention relate to a possible thyroid problem that can present without any clear symptoms & may be suspected by results of the 1st or 2nd newborn screen or other finding. Since the disorder can produce unrecognized damage long before it shows symptoms, pro-active testing is standard care.

Routine screen: All babies in the us are screened for hypothyroidism. It may be that she is having a routine screening.
