The newborn heel blood test for phenylketonuria is only a screening test, and the diagnosis needs to be confirmed based on the relevant auxiliary tests, etc. After diagnosis, it is usually not curable, but the prognosis of early intervention is good.
The heel blood test for phenylketonuria is required after the birth of a newborn, and if the screening test shows a high level of phenylketonuria, the child’s venous blood needs to be rechecked at the same time, as well as the blood needs to be genetically tested to confirm the diagnosis.
If a newborn is diagnosed with phenylketonuria, there is usually no cure. Phenylketonuria is usually an inherited metabolic disease, and there is no cure for the disease, but symptoms can be avoided by treating the disease with a diet that is strictly low in protein and phenylalanine.
Generally speaking, if the disease is treated in time, it may not show obvious symptoms and may not affect the child’s normal life. However, most parents do not realize the seriousness of the problem, so most children with phenylketonuria do not receive timely treatment, do not develop good dietary habits, and finally the child develops different degrees of slow development, mental retardation and other symptoms.
If a newborn is diagnosed with phenylketonuria, it is recommended that early treatment be standardized to reduce the adverse effects of the disease.
