Dr Vandan H KumarFather of a 7 yr 4 m old boy1 Year agoA. The Guthrie test, also called the PKU test, is a diagnostic tool to test infants for phenylketonuria a few days after birth. To administer the Guthrie test, doctors use Guthrie cards to collect capillary blood from an infant's heel, and the cards are saved for later testing.
if you missed the test then also it's fine no need to worry and you can skip the test now

You should check with your doctor they’ll tell you what is the exact thing what is the test for and when do you need to get it done so kindly consult your doctor for that whatever doubt you have associated with this particular test the doctor would be able to help you on that
