Phenylketonuria test
Phenylketonuria test
Blood is routinely drawn from newborn infants for testing. Blood is obtained by a heel stick and collected on a special blotter paper. Routine testing includes phenylketonuria and blood type. Many hospitals include other tests such as thyroid function, hemoglobin S (sickle cell disease), or may test for other blood disorders (hemoglobinopathies). Testing can be tailored to the local population, determining what routine testing should be done.
