The Bilirubin Total and Direct test results are primarily used to evaluate what?

The results of the Bilirubin Total and Direct tests are primarily used to assess liver function. Bilirubin is a yellow compound that is produced during the normal breakdown of red blood cells. It is processed by the liver, where it is conjugated (made water-soluble) and then excreted in bile. When evaluating these test results, a healthcare provider can determine how well the liver is performing its functions, particularly its ability to metabolize and eliminate bilirubin from the bloodstream.

Elevated levels of bilirubin can indicate liver dysfunction, such as hepatitis, cirrhosis, or biliary obstruction, where the normal flow of bile is hindered. Therefore, when interpreting Bilirubin Total and Direct results, clinicians can gain valuable insights into the health of the liver, helping to diagnose or monitor liver-related diseases.
