okk... thanks to all

It's checked once. If it is normal. However if the levels are not in the normal range and your doctor has you on medications then as advised by the doctor.

if u are taking medicine it is to be tested as the dr. says and mine was done every 2 or 3 months as thyroid is the most important in child's growth

mine was checked only one time and that too in the starting...

i thing only one tym
