What is the reason for collecting blood from the soles of the baby's feet?

In life, we welcome many new lives every day. The arrival of babies makes the family happier. Some young people who are new parents have no experience in taking care of babies, so they often make some small mistakes and do not understand some problems well. Normally, after the baby is born, it is necessary to draw blood from the soles of the feet. At this time, the baby will cry and make the parents very uncomfortable. So what is the reason for drawing blood from the soles of the feet after the baby is born?

First, what is the reason for collecting blood from the baby's heel when it is born? The baby's heel blood will be collected within 3-7 days after birth. The main purpose is to screen and prevent children from having mental retardation. Early detection, diagnosis and treatment in the neonatal period can avoid serious harm to the baby. Therefore, parents must actively cooperate with the hospital to conduct heel blood screening according to the screening procedures.

Second, currently heel blood tests are mainly used to check for phenylketonuria (PKU) and hypothyroidism (CH). If these two diseases are not treated in time, they can cause severe intellectual disability in the baby. Phenylketonuria. Phenylketonuria (PKU) is an autosomal recessive genetic disease. It is named because the baby has phenylalanine metabolism disorder, which causes a large amount of phenylpyruvate and other metabolites to be excreted in the urine. Phenylalanine is one of the essential amino acids for the human body. Due to gene mutation, phenylalanine hydrogenase cannot be metabolized normally and accumulates in the body, causing damage to the central nervous system and a series of pathological changes. The baby will gradually develop abnormalities in the nervous system, such as hair turning from black to yellow, skin turning white, iris becoming lighter, increased muscle tone, abnormal gait, etc. My baby's urine has a very unpleasant rat urine smell. In addition, babies are prone to eczema, vomiting, diarrhea, etc. Hypothyroidism. Hypothyroidism (CH) is caused by congenital factors that reduce the secretion of thyroid hormones, leading to growth disorders and intellectual disability in babies, and is also known as "cretinism". There are no obvious symptoms in the early stages, and only through screening can it be discovered, diagnosed and treated early, so that the child can grow up healthily and be able to take on various jobs and organize a family when he grows up.

What is the reason for collecting blood from the soles of babies' feet when they are born? It is mainly used to collect blood from the soles of babies' feet, mainly for diseases with high incidence, no obvious symptoms in the early stage but with positive laboratory indicators, which can be diagnosed and treated. This makes it possible to detect some congenital metabolic defects in the neonatal period, identify suspected patients, and conduct further examinations to confirm the diagnosis, so that the children can receive early diagnosis and treatment, avoiding physical and intellectual development disorders or even death caused by irreversible brain lesions.
