Total Bilirubin
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Total Bilirubin measures the sum of conjugated (direct) and unconjugated (indirect) bilirubin in the blood. It is a primary indicator of the liver's ability to process and excrete breakdown products of hemoglobin. Within a Liver Function Test (LFT), it helps differentiate between hepatobiliary disease, hemolysis, and biliary obstruction. Elevated levels often manifest clinically as jaundice.

Why Context Matters
Isolated elevation might be caused by Gilbert's Syndrome (a benign genetic condition) rather than liver disease. Strenuous exercise, prolonged fasting, or specific medications (e.g., anabolic steroids, certain antibiotics) can falsely elevate levels.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
