The most sensitive and specific test for the diagnosis of feline EPI is the feline trypsin-like immunoreactivity assay('''fTLI'''). The values are greatly reduced as compared to normal animals. Values '''<8µg/l''' in cats are considered diagnostic. This test must be carried out after withdrawing food for several hours. Unfortunatley the fTLI assay is only available from specialist laboratories, other tests are available but are often inconvenient and expensive.
