- What is Bilirubin?
Bilirubin is a yellow compound created when the body breaks down old or damaged red blood cells. After bilirubin is produced, it travels to the liver, where it is processed and excreted from the body through bile and urine. - Why is a Bilirubin Blood Test Important?
A bilirubin blood test is a key indicator of liver function. The liver’s job is to filter and remove bilirubin from the bloodstream. If the liver is not working properly, bilirubin levels in the blood may rise, leading to jaundice, a condition where the skin and eyes become yellow. This test helps diagnose and monitor liver diseases and conditions affecting the bile ducts. - Normal and Elevated Levels:
- Normal: Total bilirubin levels are typically under 1.2 mg/dL.
- Elevated Levels: When bilirubin levels are higher than normal, it can indicate liver or bile duct issues, such as:
- Hepatitis: Inflammation of the liver that affects bilirubin processing.
- Cirrhosis: Scarring of the liver tissue that impairs function.
- Gallstones: Blockages in the bile ducts can prevent bilirubin from being eliminated.
- What Do Elevated Bilirubin Levels Mean?
High bilirubin levels can be a sign of liver disease, bile duct obstruction, or other underlying health issues. Jaundice is the most noticeable symptom, but other symptoms may include dark urine, pale stools, and fatigue. - Why Regular Testing Matters:
Regular bilirubin testing is crucial for people at risk of liver disease or those experiencing symptoms of jaundice. It helps detect liver dysfunction early, allowing for timely intervention.
Recommended Tests:
- Total Bilirubin Test – Measures the total amount of bilirubin in your blood to assess liver function.
- Alanine Aminotransferase (ALT) Test – A liver enzyme test that complements bilirubin testing to evaluate liver health.
