Ascitic Fluid Bilirubin
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Measuring bilirubin in ascitic fluid is a specialized test used to diagnose biliary perforation or leak into the peritoneal cavity. In a healthy state, ascitic bilirubin is lower than serum bilirubin. If the ascitic fluid bilirubin is higher than the serum level (often with a ratio >1.0), it strongly suggests a 'choleperitoneum' (bile leak).

Why Context Matters
A 'traumatic tap' (blood contamination during fluid collection) can lead to falsely elevated bilirubin levels. Results must always be interpreted alongside a simultaneous serum bilirubin test to calculate the ratio.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
