When a baby is born, why do you need to collect blood from your heel?

Heel blood sampling, also known as heel blood screening, is a test that requires a baby to have heel blood collected after birth to check for disease.

After birth, babies undergo a series of tests, such as heel blood. The main diseases for which heel blood is taken are congenital hypothyroidism and phenylketonuria. These two conditions have a certain incubation period, and it is difficult to see them in the early stages of the disease, but there are indicators of these conditions in the laboratory, and if the baby has these two diseases, the doctor can test them by taking blood from the heel.

Diseases like congenital hypothyroidism and phenylketonuria, although there are the best methods, if they are not detected in time, they can cause great harm to the baby's body. Children with congenital hypothyroidism have their brain development stunted and may eventually become children with low intelligence. If there is phenylketonuria, the baby's nervous system will be abnormal, their hair, ** will change, and there will also be diarrhea, vomiting and other conditions.

If the doctor can detect the symptoms in time and help the baby**, this type of risk can be avoided in the end. That's why doctors must take blood from the heels.

Heel blood collection is particular, adhering to the principle of early detection and early **, generally in the 3-7 days after the baby is born, which is the best time to collect heel blood. At this time, the baby has already received nutrients from breast milk, and blood sampling will not cause damage to their body. The method of collecting heel blood is also relatively gentle, and there are special pieces of paper for heel blood screening in the hospital, and they are also particular about blood collection.

It is not easy to raise a baby safely, which is why parents in the world are so great.

In order to detect some special diseases, babies are generally examined after birth.

The main purpose is to check and see if there are any genetic diseases, if there are other diseases, and so on.

Newborn babies have blood taken from their heels for a physical examination.

This is a method developed by the hospital, and it is for newborns.

Because blood is drawn for some tests, it is generally the kind of disease that cannot be detected by pregnancy tests.

The Football Association examination of Cai Xiaobao is to check whether there is a congenital thyroid disease.

In this way, it is best to check whether the baby is healthy, and it is best to analyze it from the blood.

It is time to have a blood test to check for diseases.

The first thing is to check whether the body is healthy, and the other is to see if there are other genetic diseases.

How to deal with blood collection problems.

When one of the newborn babies has some serious congenital diseases, such as congenital hypothyroidism and phenylketonuria, these two diseases are likely to lead to intellectual disability if not treated early, and the severe situation will have a serious impact on the baby's acquired physical and mental health. However, according to the collection of heel blood, you can detect whether the baby itself has the probability of such important diseases, if it is suffering, it can also achieve early detection, early diagnosis, and early treatment, which can prevent more serious damage to the baby. At the same time, the collection of heel blood can also be used to make some ** analysis of all the diseases that are likely to occur.

The main purpose of collecting heel blood from newborn babies is to better screen for genetically inherited respiration diseases and endocrine disorders, such as congenital adrenal hyperplasia, phenylketonuria, congenital hypothyroidism, etc. This disease will cause obvious harm to the baby's central nervous system, digestive tract, endocrine disorders, growth and development, etc., so that the baby has intellectual disability, liver function hazards, physical development retardation, etc., not only endangering the baby's growth and development, learning and training, daily life, etc., but also will continue to produce heavy pressure on the family and its social development. Therefore, the heel blood test for newborn babies can diagnose this disease at an early stage, and prevent irreversible and serious harm to the baby's key human organs, such as the human brain and liver.

The key to the new screening of heel blood in newborn infants are congenital hypothyroidism and phenylketonuria. If these two diseases are not treated immediately and regularly, it is likely to cause the child's nervous center and IQ to decline, and in more serious cases, it is likely to cause the child's intellectual disability. Newborn infant heel blood screening is a test in which heel blood is collected 72 hours after the baby is born.

The key is for diseases with a high prevalence, no significant initial illness but positive laboratory index values, which can be diagnosed and treated.

The baby's heel blood is collected to better screen for hypothyroidism, phenylketonuria and deafness genes, which can prevent intellectual disability caused by hypothyroidism, mental retardation caused by phenylketonuria, and English hearing loss caused by deafness genes. Usually, newborn babies must have heel blood taken 72 hours after birth for screening. If there is an abnormality in thyroid function in the heel blood, a venous blood follow-up examination must be carried out after the baby is full of age to check thyroid function.

If there is still an abnormality, it is necessary to provide drug intervention as soon as possible under the guidance of a doctor, and phenylketonuria is an autosomal recessive genetic disease, which also needs to be prevented initially.

The purpose of collecting bamboo poles is to screen children with congenital hypothyroidism, and if they are not timely, they are likely to have problems such as mental decline and developmental delay.

The main purpose is to check whether the child has any symptoms, or what the child's physical condition is, and also to ensure the child's physical health.

Because in this way, we can comprehensively analyze the diseases that the baby may get, and can save the baby's life when the baby has abnormal conditions.

The key purpose of heel blood collection is to test for neonatal inborn metabolic disorders, such as congenital hypothyroidism and phenylketonuria and congenital adrenal hyperplasia. It is important to note that this kind of examination is only a screening, and there is a possibility of misdiagnosis, and if any problems are found, further examination is required. Achieve early diagnosis and early **, and reduce the direct impact of the disease on the development of newborns.

Seeing the baby crying in pain when the blood was drawn, the hearts of the parents also hurt. In fact, the key to collecting heel blood for small babies is to have a relatively high incidence and <>

However, there is no significant condition in the initial stage, but the laboratory has a positive index value, which can be diagnosed and treated. Heel blood collection for the baby is not because the baby has any disease, but it is necessary to clear some very likely diseases for the baby, and this disease can be cured if it can be detected at an early stage. If you don't notice it, it will affect your child's life.

There is also a key feature of these diseases: there are basically no symptoms in the case of birth, and it takes a few months to have significant clinical manifestations visible to the naked eye, but the effect is very poor when the symptoms come out.

Congenital hypothyroidism and phenylketonuria can harm the nerve center of the human brain, causing IQ dementia, and the neuronal cells of the human brain are irreversible after being harmed. At this stage, the new items in the screening category in China include congenital hypothyroidism and phenylketonuria. If left untreated, congenital hypothyroidism and phenylketonuria can lead to severe mental retardation, but if early detection, early diagnosis and early ** can be done in the neonatal period, <>

This can prevent visible damage to the child. Therefore, it is important not to underestimate a small amount of heel blood, which can change the life of a baby. The plantar blood supply of newborns is more colorful, and it is very easy to collect blood strips for sufficient testing by selecting the heel; The relativity of neonatal heel pain is not so sensitive, and the whole process of blood drawing can minimize the pain of neonates. Newborns generally have higher flexor muscles, and their arms are generally tightened, and finger blood is not easily collected.

The main items of heel blood examination in neonates are phenylketonuria and congenital hypothyroidism; Sub-items include congenital adrenal hyperplasia, glucose-6-phosphate dehydrogenase deficiency. Neonates are usually collected from the heel 72 hours after birth, after adequate breastfeeding, when the protein load is low and the false negative phenylketonuria screening can be avoided.

This is to screen for some genetic diseases, so that the specific condition of the child can be observed.

It is mainly aimed at diseases with high incidence, no obvious symptoms in the early stage but positive laboratory indicators, which can be diagnosed and can be **.
