Within 72 hours after birth, babies need to have a heel prick blood test, primarily to screen for certain genetic and metabolic disorders. However, this heel prick test is only a preliminary screening. If the results indicate any issues, it is recommended to return to the hospital as soon as possible for further evaluation.
