Question

My child has been acting up lately, crying and fussing non-stop, and even hospital checks haven’t helped. What kind of test is used for newborn phenylketonuria screening?

Answer

The newborn phenylketonuria screening generally requires blood to be carefully examined through venipuncture. If a child’s growth and development are abnormal, it is often due to blood diseases, and the specifics should be based on the results. It is advised not to have excessive mental stress. If no oral medication or other issues were taken during pregnancy, there should be no major problems. It is important to pay close attention and observe the child carefully for any other discomforts.
