It is important that biliary tract rupture are diagnosed promptly as the peritonitis becomes more severe with time.

The affected animal may show few clinical signs initially besides [[Icterus|icterus]] and evidence of an [[Exudate|ascites]]. As chemical peritonitis develops, the animal may show signs of:

Analysis of blood samples may show evidence of an acute inflammatory response, with a neutrophilic '''leucocytosis''' and elevated fibrinogen. The neutrophilia may have a left shift or, in severe cases, it may have a degenerative right shift. Cases with a very marked inflammatory response may develop a '''leukaemoid response''' with mobilisation of very large numbers of neutrophils from the bone marrow pools.

Aspiration and cytological analysis of fluid from the abdomen will reveal it to be a form of [[Exudate|exudate]] with an evident green colouration. The fluid may contain mucinous or fibrillar material and it should be expected to have a bilirubin concentration at least twice that of serum<ref>Owens SD, Gossett R, McElhaney MR, Christopher MM, Shelly SM.
