Newborns need to check for plantar blood, what diseases are it mainly used to check for?

Phenylketonuria.

Phenylketonuria (PKU) is an autosomal recessive disorder. It is named because of the phenylalanine metabolism disorder in newborns, and a large amount of metabolites such as phenylpyruvate are excreted in the urine. Phenylalanine is one of the essential amino acids in the human body, and after ingestion into the body, some of it is used by the body for protein synthesis, and the rest is converted into other substances.

Phenylalanine cannot be metabolized normally in the body of newborns, but accumulates in the body, causing damage to the central nervous system and a series of pathological changes.

Newborn plantar blood examination is mainly thyroid hormone, that is, to see if the child has hypothyroidism, if the thyroid hormone secretion is insufficient, it will have a great impact on the development of the child's nervous system, if it is not timely, it will cause cretinism, so newborn plantar blood collection in order to check whether there is hypothyroidism, if the plantar blood sampling screening is abnormal, then you need to go to the hospital for further examination, and it is necessary to be timely after diagnosis.

Neonatal heel blood screening refers to the examination of heel blood collected 72 hours after the birth of the baby, mainly for diseases with a relatively high incidence rate and no obvious symptoms in the early stage, but there are positive laboratory indicators that can be diagnosed and can be the best. At present, the items included in the screening scope in China are congenital hypothyroidism and phenylketonuria, rather than checking for any blood diseases. These two diseases, if left untimely**, may cause severe mental retardation in the baby.

Therefore, it is recommended to detect early, diagnose early, and avoid serious harm to the baby. The heel blood collection time is generally within 3 to 7 days of birth, and the newborn is fully breastfed, and it should not be more than 20 days after birth for those who have not collected blood for various reasons.

Newborn heel blood can be used to screen for a number of inborn metabolic defects, usually for all five: phenylketonuria, hypothyroidism, congenital adrenal hyperplasia, glucose-6 phosphate dehydrogenase deficiency, and thalassemia. Among them, hypothyroidism and phenylketonuria are necessary to do, and parents can make their own decisions after considering whether to do the rest or not.

Therefore, blood is generally collected in the heel of the neonate to screen for congenital hypothyroidism and phenylketonuria. These diseases are usually asymptomatic in the early stages, and the inherent clinical symptoms usually do not appear until 6 months of age, and gradually worsen.

The results of the screening can be found on the official website of the local health and family planning commission. Take Beijing as an example: open a browser on a computer or mobile phone and enter the address of the Beijing Health and Family Planning Commission to open the web page.

Newborn plantar blood is tested for neonatal inherited metabolic diseases. For example, congenital hypothyroidism, phenylketonuria. Congenital hypothyroidism is a condition that causes growth remission and mental retardation.

This disease can only be detected early by screening, and early ** can make the baby grow healthily. Phenylketonuria is a condition that predisposes to mental retardation. Through screening, early diagnosis and **, this disease allows the baby to live like a normal person.
