What tests are needed to further define Jaundice?

Most of the time, a meter will first be placed to the baby’s forehead as a screening test. If the meter level is elevated, then it will be necessary to do a blood test to measure the bilirubin level. A test for the blood type of the infant is generally necessary to determine if it is compatible with the mother’s blood type, but most of the time this is done on blood from the umbilical cord at the time of delivery. If there is a concern about rapid destruction of the red blood cells, a blood count may be necessary.
