Question

Why is it necessary to take three drops of blood from the bottom of a newborn’s feet for disease screening? If the hospital notifies a need for repeat testing and the report shows two abnormalities, does this mean the issue is severe?

Answer

Newborn disease screening is primarily conducted to rule out conditions such as phenylketonuria, congenital hypothyroidism, glucose-6-phosphate dehydrogenase deficiency (also known as ‘sickle cell anemia’), and congenital adrenal hyperplasia. When doctors recommend repeat testing, it is usually necessary to confirm the results and provide appropriate treatment. Early detection and treatment of these diseases are crucial for the healthy growth of the baby. It is advised to undergo regular screenings and follow the doctor’s recommendations to ensure the baby receives the best care. Additionally, diseases that may affect the baby’s nervous system, such as infantile spasms, should be monitored and treated early to mitigate potential severe consequences.
