What is the newborn plantar blood test

Newborns are screened with plantar blood collection for four inborn genetic metabolic disorders; congenital hypothyroidism, adrenocortical hyperplasia, phenylketonuria, and phosphate dehydrogenase deficiency.
After 72 hours of birth, heel blood is usually collected to screen for congenital hypothyroidism, congenital adrenal hyperplasia, phenylketonuria, and phosphodehydrogenase deficiency, with the goal of early detection, timely intervention, and treatment.
The goal is early detection and timely intervention and treatment so that the baby’s physical and intellectual development will not be affected.
If the results of the plantar blood test are positive, parents are advised to take their babies to the hospital for review as soon as possible. If the result is still the same after the review, you should cooperate with the doctor to start the treatment as soon as possible.
