Tests and diagnosisBy Mayo Clinic Staff
Your doctor will likely diagnose infant jaundice on the basis of your baby's appearance. However, your doctor will need to measure the level of bilirubin in your baby's blood. The level of bilirubin (severity of jaundice) will determine the course of treatment.
Tests to determine jaundice include:
- A physical exam
- A laboratory test of a sample of your baby's blood
- A skin test with a device called a transcutaneous bilirubinometer, which measures the reflection of a special light shone through the skin
Your doctor may order additional blood tests or urine tests if there's evidence that your baby's jaundice is caused by an underlying disorder.
