$ 18.00 AUD
The Direct Bilirubin Test measures the levels of conjugated bilirubin in the blood. Bilirubin is a yellow pigment produced during the breakdown of red blood cells. The liver processes bilirubin into its conjugated (direct) form for excretion. Elevated direct bilirubin levels may indicate liver disease, bile duct obstruction, or impaired bilirubin clearance. This test is used to assess liver function and diagnose conditions such as hepatitis, gallstones, and cholestasis.
