*'''Low protein''' and '''low celularity'''
*Clear
*Specific gravity <1.018
*Total protein < 25g/L
*Nucleated cells <0.5 x 10e9/L
*[[Mesothelial cells|Mesothelial cells]], [[Macrophages - WikiBlood|macrophages]], low numbers of non-degenerate neutrophils
*Typically very high volume of fluid

*'''Due to:'''
**Decreased colloid osmotic pressure
**Renin - angiotensin system activation
**Hypoalbuminaemia secondary to glomerular or hepatic disease or GI loss (globulins also low)
**Prolonged portal hypertension and formation of secondary collateral circulation
