Before a baby can be treated, the exact cause of an infant's jaundice must be determined. In some cases, a careful examination by a pediatrician is all that is needed. In other cases, blood tests may be required.

• The serum bilirubin level may be checked. Based on this test, the doctor may request that more tests be ordered. Some health care practitioners use a device that measures transcutaneous bilirubin such as the BiliCheck, so there is no need to draw blood.
• A Coombs test checks for antibodies that destroy an infant's red blood cells.
• A complete blood count may be ordered.
• A reticulocyte count is performed to be sure your baby is making enough new red blood cells.
• Certain red blood cell diseases are found in people of Mediterranean descent. In such cases, it may be necessary to check blood samples for a condition known as G6PD deficiency.
