Exams and Tests

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.

• First, the total serum bilirubin level will be checked. Based on this test, the doctor may request that more tests be done.
  
  
  • A Coombs test checks for antibodies that destroy an infant's red blood cells.
    
    
  • A complete blood count may be done.
    
    
  • A reticulocyte count checks 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.
