What is the relationship between the baby s lifelong intellectual development and his heel blood ?

Usually the heel blood is collected after 3 days of birth, and the premature baby is generally collected within 20 days, mainly to check whether the child has phenylketonuria and whether the baby has hypothyroidism. If the heel blood test is collected 40 days after the baby is born, it will affect the accuracy of the test results and delay the baby as soon as possible**.

After the baby is born, the heel blood should be collected to check whether the body has an underlying disease, many babies will cry when the blood is drawn, some parents can't bear to see such a small baby being pricked with a needle to draw blood, will delay the collection of heel blood for the baby, and even drag the child to the hospital after the full moon examination. So, can a 40-day-old baby still have heel blood collected?

The main purpose of collecting infant heel blood is to check whether the baby has phenylketonuria, and at the same time to understand whether the baby's thyroid function is reduced. In general, heel blood should be collected at the time of discharge from the hospital, and if the baby is born prematurely, the heel blood should be collected within 20 days of the baby's birth. It is obviously too late to collect heel blood 40 days after the baby is born, and it is difficult to guarantee the accuracy of the test results.

In addition, after the baby's heel blood collection, the test results will not be known immediately, usually if the screening results are normal, parents will not receive a notice from the hospital, if the results are different, the hospital will notify parents to take their children to the hospital for a check-up, re-examination is very important, parents must not ignore, especially the baby with abnormal results of both examinations, must go to the re-examination regularly.

In addition, the thyroxine secretion in the heel blood test item is very important for the baby's future physical and intellectual development, if the heel blood test results are insufficient thyroxine secretion, the baby should be supplemented with thyroid hormone in time according to the doctor's guidance, early detection is very helpful to the baby's health, and the mother must not ignore the importance of the heel blood test.

About the 40-day baby can still collect heel blood here, for the healthy growth of the baby, the mother must keep in mind the baby heel blood collection time, if missed, should explain the situation to the doctor, and then according to the actual needs of the baby, regularly check the baby's physical condition. If the results of the heel blood test are different, you should actively cooperate with the doctor** to reduce the adverse effects of the disease on the baby.

In addition to leaving footprints, there is one thing that is heavier than leaving footprints, that is, to keep foot blood, that is, to do a heel blood test, which is not a simple routine, it is related to the development of the child's body and intelligence in the future.

The purpose of heel blood is to screen for congenital diseases, and 48 hereditary diseases can be preliminarily judged through the laboratory test of heel blood, but under normal circumstances, hospitals will not do so much screening, and only a few common diseases will be screened, the most important of which are congenital hypothyroidism and phenylketonuria.

Therefore, the new birth of the mother must cooperate with the hospital blood collection, generally after the baby is born 72 hours later, the hospital will carry out blood collection, if the new mother is discharged in advance, it is best to take the initiative to go to the hospital, and must not exceed seven days, this time is also very critical, not to forget. Newborn mothers must pay attention to the fact that the baby should be fed enough milk before blood collection, which is related to the accuracy of the screening results and is very important. After blood collection, the mother should wait patiently, because the screening results will come out in about a month, during which special attention should be paid to the fact that if the hospital notifies the review, it is necessary to cooperate actively in a timely manner, and must not delay or ignore it, because missing the time will bring irreparable harm to the baby.

Because the hospital notifies the re-examination, it may be that the baby's blood sample test result is positive, which indicates that the baby is suspected of suffering from these diseases, and the hospital will not notify the re-examination if the test result is negative.

Why do you need to respond to the hospital's review in a timely manner? Because the earlier these diseases are found, the earlier the likelihood is greater, specific to hypothyroidism and phenylketonuria, if the newborn is within two months of birth, then the baby's physical and intellectual development can reach a normal level in the future, and the proportion of abnormalities will increase after more than two months, so this time is very limited, and it must not be delayed, and it must be responded to in time.

Babies suffering from phenylketonuria will have yellowish hair, whitening, slight trembling hands, urine smells of rat urine, accept ** to control the baby's diet, and often change and adjust, strict medication and control protein intake.

Babies with hypothyroidism do not like to move, do not cry, love to sleep, seem to be well-behaved, have poor reaction ability, and will be disabled and mentally retarded if not timed.

Both of these can have an irreversible impact on the baby's development, but they can be detected in the screening of heel blood, so novice mothers must not take this lightly.

It is mainly to screen children for phenylketonuria, congenital hypothyroidism, galactosaemia, adrenal hyperplasia, glucose-6-phosphate dehydrogenase deficiency and other inherited metabolic diseases. 1.Babies with phenylketonuria will have an unpleasant smell of rat urine in their urine, accompanied by symptoms of particularly thin yellow hair, and if delayed**, then the child's intellectual impairment will be irreversible.

2.Congenital hypothyroidism, commonly known as "cretinism", is a disease caused by a decrease in the secretion of thyroxine or a complete deficiency of thyroxine.

Therefore, these two diseases can cause serious mental retardation in the baby if they are not timely, but if they are detected early, diagnosed early, and early in the neonatal period, they can avoid serious harm to the baby. Generally, the results are available within about a month after the heel blood is collected, if the test is positive, the related disease is suspected and needs to be retested, then the blood must be collected again, and if the test report is negative, there is no need to take blood again.

This screening is done more than 72 hours after the birth of the baby and within the full month. It is mainly aimed at the diagnosis of diseases, which is convenient for early detection and **. If detected late, the infant may have severe growth and development disorders and mental defects.
