The panel of laboratory tests available for diagnosis of @entity344 in @entity235 and @entity468 is wide, and, recently, several new tests have been developed. This article will focus on advances in laboratory tests that are available for the general practitioner for diagnosis of @entity344 . Laboratory tests for diagnosis of gastric and intestinal infectious diseases include fecal parasite screening tests, enzyme-linked immunosorbent assays for @entity1681 , and some specific bacterial tests like fluorescent in situ hybridization for identification of specific bacteria attached to the intestinal epithelial cells. Serum concentrations of @entity1501 and @entity2186 are markers of intestinal absorption, but are also changed in exocrine @entity3210 and intestinal @entity6124 . Hypocobalaminemia is common in GI and @entity660 . Decreased serum trypsin-like immunoreactivity is a very sensitive and specific test for the diagnosis of exocrine @entity3210 in @entity235 and cats. Serum pancreatic lipase is currently the most sensitive and specific test to identify @entity660 and acute @entity788 . However, serum canine pancreas-specific lipase is less sensitive in @entity235 chronic @entity788 . Increased serum trypsin-like immunoreactivity is also specific for pancreatic damage but is less sensitive. It is very likely that further studies will help to better specify the role of these new tests in the diagnosis of @entity235 and feline @entity660 .
