*4.1.8 Triglycerides*

An elevated triglyceride concentration in ascetic fluid above 2.2 mmol/l indicates chylous ascites [38]. Chylous ascites is common in neoplastic cases although it may occur in 6% of cirrhosis [40].

## *4.1.9 Urea and creatinine*

Elevated levels in urea and creatinine concentrations in ascetic fluid indicate prerenal failure due to peritoneal absorption of urea [41]. Urinary ascites is often associated with bladder changes and urethra obstruction [41, 42].
