What is the normal value of TSH for newborns?

Neonatal TSH refers to whether the baby's thyroid function is normal. Generally speaking, a normal neonatal TSH means that the baby's thyroid is healthy and there is no thyroid disease. Under normal circumstances, the normal TSH index of a newborn is around 0.270. If a pregnant woman develops a disease during pregnancy, it will easily lead to a high TSH index in the newborn. Regular examinations and care are required.

Heel blood sampling for newborn screening is a very important examination item. Heel blood sampling must be performed 72 hours after the baby is born. The heel blood mainly checks phenylketonuria (PKU for short) and hypothyroidism (CH for short). If these two diseases are not treated in time, it can cause severe intellectual disability in the baby. However, if they are discovered, diagnosed and treated early in the neonatal period, serious harm to the baby can be avoided. What is the normal range of heel blood TSH?

Newborn heel blood screening can detect whether the newborn baby has congenital blood-related diseases. A heel stick is collected when the newborn is more than 72 hours old and less than one month old to screen for two disorders: congenital phenylketonuria and hypothyroidism. The main symptoms of these two diseases are stupidity, slow reaction, developmental delay, etc. Once diagnosed, the state provides free treatment, with a cure rate of over 95%. If you don't get screened, you won't be able to cure the disease if you get it in the future. Generally, the results of heel blood collection will be available within about one month. If the test result is positive, it means that a related disease is suspected and a re-examination is required, then blood will have to be drawn again. If the test report is negative, there is no need to draw blood again.

In the newborn heel blood screening, there is a screening called TSH thyroid-stimulating hormone, but many parents do not know what the normal value of heel blood TSH is after getting the results. The reference range of normal heel blood tsh is 0.270~4.200uIU/L, but if you want to know the specific situation, it is best to consult a specialist.

Neonatal tsh. Many parents are confused when they see this word. They don’t know what this word means. In fact, neonatal tsh refers to thyroid function. Generally speaking, the approximate value of tsh is within the range of 0.35-5μU/mL. It is worth noting that, under normal circumstances, some hormones in newborns are higher than those in adults.

F3 and F4 generally refer to indicators of thyroid function. If there is only a slight improvement, there is no need to worry and you can wait until your baby is 1 to 2 years old for a recheck. However, if the test shows that TSH is at least twice or more than normal, then T3 and T4

If it also rises, then it is very likely that the baby has a problem with hyperthyroidism.

When you go to the hospital for a check-up, the hospital will draw blood from the soles of your feet for examination. This examination is mainly to rule out congenital hypothyroidism. If it is congenital, you need to go to the hospital for a timely follow-up examination. If necessary, the hospital will use medication to control it in time to avoid affecting the intelligence of the newborn. In addition, when the TSH value is high and no other special symptoms are found, doctors sometimes consider other possible causes, such as subclinical hypothyroidism. Generally speaking, if blood lipids and cholesterol are not elevated, no special treatment is required. However, this requires a semi-thyroid function review every six months or so to check for any specific changes. If there are abnormal indicators such as T3 and T4, you should seek medical attention immediately.
