What is MSMS Screening for Newborn Diseases?

Question

Do newborns need to undergo MSMS screening? Why?

Answer

MSMS screening is a method used to detect if newborns have certain genetic metabolic diseases. This test is typically conducted within 2 to 3 days after the newborn’s birth, by collecting a heel prick blood sample. The MSMS screening can detect multiple genetic metabolic diseases, including glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency), phenylketonuria (PKU), and hypothyroidism, among others. If these diseases are not discovered and treated promptly, they may have severe impacts on the newborn’s health and development. Therefore, many countries and regions include MSMS screening as part of the routine newborn health check-up programs.
