DIRECT BILIRUBIN Test

The Direct Bilirubin test measures the level of conjugated bilirubin in the blood. Bilirubin is produced when red blood cells are broken down. The liver processes bilirubin into a water-soluble form called direct or conjugated bilirubin, which is then excreted through bile.

An elevated bilirubin level can occur when the liver cannot properly process or excrete bilirubin or when bile flow is blocked. The test is commonly used as part of a Liver Function Test (LFT) and is often interpreted along with total bilirubin, indirect bilirubin, ALT, AST, ALP, and GGT.

This Test is Recommended for Individuals:

• Individuals with yellowing of the skin or eyes (jaundice)
• Patients with dark urine or unusually pale stools
• People being evaluated for liver disease
• Individuals with suspected bile duct obstruction
• Patients with abnormal liver function test results
• People experiencing unexplained abdominal discomfort, nausea, or fatigue
• Patients being monitored for an existing liver or biliary condition

FAQs

1. What does Direct Bilirubin measure?
It measures conjugated bilirubin, the form of bilirubin that has been processed by the liver and is ready to be excreted through bile.

2. What causes high direct bilirubin levels?
High direct bilirubin can occur with liver disorders, bile duct obstruction, cholestasis, hepatitis, and certain other conditions affecting bilirubin processing or bile flow.

3. What is the difference between direct and indirect bilirubin?
This is conjugated and processed by the liver, while indirect bilirubin is unconjugated and has not yet been processed by the liver. Measuring both can help healthcare providers identify possible causes of abnormal bilirubin levels.
