According to the experimental results of neonatal hemolysis, it can be judged that the experimental results of neonatal hemolysis are positive. The free experiment is to incubate the child's plasma with standard A, B and O blood cells to see if there is agglutination, while the release experiment is to wash the antibody bound to newborn blood cells by heating or other methods, and then incubate the washed things with standard ABOx blood cells. If agglutination occurs, it is positive.
Newborn hemolysis screening in most hospitals in China is congenital hypothyroidism, phenylketonuria and hearing screening. The purpose of neonatal screening is to screen out the disease before the child has obvious symptoms, and give timely treatment to prevent harm to the child. For example, after screening, children can be given low phenylalanine milk powder instead of ordinary milk powder or breast milk, which can reduce the accumulation of phenylalanine in the brain and cause damage to the brain.
