Why are newborns tested for heel blood? The reasons are so important. Does mom know?

1. Why should newborns collect enough blood? As mentioned above, heel blood is collected for newborns to screen babies for diseases. This is a mandatory checkup for newborns. It is usually collected within three days to a week after the baby is born. For some infants not collected due to special reasons, no more than 20 days at the latest. The general procedure is as follows: newborns collect heel blood in the birth hospital, and then send the collected blood to a special disease screening center for examination, so as to discover hidden diseases in time and treat them as soon as possible.

Infants with phenylketonuria appear to have thin and yellow hair on the surface, which is likely to cause intellectual developmental disorders in infants; congenital hypothyroidism is called dementia. If not detected and treated in time, it will not only affect children's IQ, but also lead to developmental disorders and other diseases pku diet.

3. How to know the result of the baby's heel blood? Generally speaking, the result of the heel blood test will come out within 30 days. The hospital will contact the parents based on the phone number left by the baby's parents and inform the parents of the screening results. If the result is negative, it means everything is normal. On the contrary, it is necessary to go to the hospital for further examination, and the hospital will inform the address and contact information of the continued examination. However, it is important to point out that receiving a re-examination notice from the hospital does not necessarily mean that there is something wrong with the baby. Sometimes, this may be because the first blood draw was insufficient and the test results need to be reconfirmed. So don't panic when parents are notified of a review. They must take the child to the hospital as soon as possible!
