Creatinine
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Creatinine measurement in Ascitic Fluid is a specialized diagnostic tool used primarily to identify 'uroperitoneum' (urine leaking into the peritoneal cavity). Under normal circumstances, creatinine levels in ascitic fluid should be equivalent to serum creatinine levels. If the fluid creatinine is significantly higher than the serum level (usually a ratio > 2:1), it confirms that the abdominal fluid is actually accumulated urine resulting from bladder or ureter trauma or perforation.

Why Context Matters
Interpretation requires a simultaneous serum creatinine test. Results can be misleading in patients with severe renal failure or those who have received recent IV hydration. A second opinion or imaging (CT cystogram) is vital if the source of the fluid is ambiguous.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
