In most states, all newborn infants have a blood
test to screen
for thyroid problems (among other possible metabolic problems). The state newborn screen should detect whether your baby has abnormal TSH levels. In addition, the pediatrician will be monitoring your baby for any clinical signs of hyperthyroidism, including irritability, rapid heart rate, breathing problems, stooling issues, or feeding problems.
