Why is newborn screening tested?
Hundreds of years ago, it was found that there were some babies born that seemed normal at birth, but later found out that their physical and mental retardation could even die because these babies were infected. Metabolic, endocrine, and genetic diseases have not been detected for treatment. For one simple reason, these conditions are often difficult to detect clinically. Therefore, only specific disease screening tests can help early detection and timely treatment of babies.
Since 1960, BS. Robert Guthrie, a pioneer in the field of newborn screening testing, found a way to screen for newborns after he gave birth to a child with mental retardation. With this method, he helped detect and treat hundreds of seemingly hopeless babies.
Faced with this great benefit, the newborn screening program is gradually expanding to many countries around the world. Implementation in the Americas began in the 1960s, Europe in the 1970s, Asia in the 80s, 90s and Vietnam in recent years. The total number of neonatal screening diseases today has risen to close to 30.
The goal of the program is to screen for early detection of neonatal diseases so the more babies are tested, the lower the chance of surviving the disease and fewer children will be affected physically and mentally later. Children’s quality of life is improved.
Newborn screening only requires a few drops of dry blood taken from the child’s heel (at full age) to be placed on a blotting paper sample for early diagnosis.
