Tests and diagnosis

By Mayo Clinic Staff

If your doctor suspects Gilbert's syndrome because you have unexplained jaundice or blood tests for other conditions show elevated bilirubin levels, he or she will examine you and ask about symptoms of liver disease, such as abdominal pain or dark urine.

Your doctor may recommend more blood tests to rule out other liver problems that can cause elevated bilirubin. Common blood tests include:

  • Complete blood count
  • Liver function tests

The combination of normal blood and liver function tests and elevated bilirubin levels is an indicator of Gilbert's syndrome. No other testing usually is needed, although genetic testing can confirm the diagnosis.
