Bilirubin Test

The Bilirubin Test is a diagnostic test that measures how much bilirubin is in the blood. Bilirubin is a yellow pigment produced by decomposing red blood cells. This is a significant indicator of liver health. Therefore, it is important to understand when a bilirubin test is necessary and what results may indicate about your health.

What does Bilirubin measure?

Measuring bilirubin levels can help diagnose jaundice, liver diseases, and other medical conditions. Bilirubin is a yellow pigment that is produced by the breakdown of heme which is an iron-containing molecule that is important for many biological processes. Bilirubin is measured to determine if someone has anaemia, liver disease, or jaundice. It is also used to help diagnose other conditions such as bile duct obstruction, hemolytic anaemia, and Gilbert's syndrome. Bilirubin levels are important indicators of a person's health and can help doctors determine the cause of certain symptoms.

Types of Bilirubin Tests

A bilirubin test measures the overall level of bilirubin. There are two ways of tests - indirect and direct -

  • Indirect bilirubin refers to the levels of bilirubin due to the direct decomposition of RBC.
  • Direct bilirubin is the level of bilirubin present post-metabolism in the liver.

Normal Level for adults fall within the range of:
  1. Direct bilirubin: < 0.3 mg/dL (less than 5.1 umol/L)
  2. Total bilirubin: 0.1 to 1.0 mg/dL (1.71 to 20.5 umol/L)
Above 1.2 mg/dL is considered a high level.
