Pancreatitis is implicated in up to 40 % of acute-abdomen ICU admissions and carries reported case-fatality rates of at least 8.8%. Its clinical picture — vomiting, lethargy, vague abdominal pain — overlaps dozens of differentials, so under- and over-diagnosis is easy. That makes objective testing the keystone of a sound pancreatitis diagnosis. But testing for canine pancreatitis isn’t simple, and there’s a whole range of tests available. So let’s see what we’ve got...
Whether it’s truly acute or acute-on-chronic, pancreatitis cases often come in with vague – though serious – signs, such as vomiting, anorexia, abdominal pain, lethargy, and dehydration. Your history taking should focus particularly on medical history (prior episodes, concurrent diseases, current medications) as well as diet (high-fat diet, or recent access to high-fat foods) to tease out contributing factors.
Measures pancreatic lipase immunoreactivity (PLI). Still the benchmark assay. Sensitivity 71–85 %, specificity 90–100 % when a ≥400 µg/L cut-off is used. Samples ship chilled; results typically next day. Downside: no rapid clinical decisions at 2 a.m.
Patient-side lateral-flow device; results in 10 min. A negative test has a high negative predictive value — helpful for ruling out pancreatitis during triage. Specificity is lower (70 – 80 %), so confirm positives with Spec cPL.
Generate a numeric cPL within 8–15 min from whole blood or serum. A 2024 head-to-head study compared SNAP cPL, Spec cPL and the newer Vcheck cPL (fluorescence immunoassay). Agreement between the three tests was impressive (0.88-0.96) and highlighted the ability of the Vcheck cPL to be used to monitor progression,
Cheap and quick, but less pancreas-specific; renal or GI disease and glucocorticoids can raise values. Use as a screen—if elevated, reflex to a cPL assay. Recent JVIM work found only 62 % specificity when DGGR was used alone.
Ultrasonography of the pancreas, abdominal radiography, and contrast CT can help to diagnose pancreatitis by ruling out conditions that present similarly, as well as identify damaged pancreas tissue and complications.
Pancreatitis is still difficult to diagnose, and clinicians should take care to combine the clinical picture and history with any test results to help reduce false positives. But new innovations in pancreatitis diagnostics – like the VCheck cPL – are making fast decision making, and prompt treatment, easier than ever.
