At a Glance

Why Get Tested?

To screen for and monitor liver disorders, such as cirrhosis. To help detect certain rare genetic disorders in sick babies and to avoid brain damage in babies who are markedly jaundiced.

When to Get Tested?

If your doctor thinks you have symptoms or signs of liver damage, liver disease, bile duct blockage, haemolytic anaemia or a liver-related metabolic problem.

Sample Required?

In adults, a blood sample from a vein in the arm; in newborns, a blood sample from a heel-prick

Test Preparation Needed?

No test preparation is necessary. The blood sample should ideally be protected from bright light before analysis.
