Is tsh weakly positive by taking blood from the soles of the feet 3 days after the baby is born?

Those with weak TSH positive in neonatal plantar blood can be reexamined. The general misdiagnosis rate is not high. There may be a mistake. Generally speaking, it is safer to review. Blood collection from the soles of newborns is a blood sample collected 3 days after birth. At this time, the hormone level in children may still be related to the maternal level. If thyroid stimulating hormone is found abnormal, it can be reexamined half a month after birth, and most of them can be reduced to normal range.
