Raised cPLI in dogs: how to interpret it in pancreatitis
8-year-old Miniature Schnauzer with vomiting, anorexia and a praying posture since yesterday, after eating barbecue leftovers.
| Parameter | Result | Reference |
|---|---|---|
| Spec cPL | 650 µg/L | ≤ 200 (200–399 equivocal) |
| White blood cells | 21,500/µL | 6,000–17,000 |
| Triglycerides | 420 mg/dL | 30–150 |
What is the most appropriate interpretation of the cPLI result?
chevron_right Show answer and explanation
A. A value of 650 µg/L indicates severe necrotising pancreatitis and a poor prognosis
The magnitude of cPLI correlates poorly with severity and prognosis. Severity is judged from clinical signs, imaging and systemic complications.
B. It must be confirmed by pancreatic biopsy before starting treatment
Biopsy is invasive and rarely indicated. The clinical diagnosis is based on compatible signs, cPLI and ultrasound, and supportive treatment should not be delayed.
C. It supports a diagnosis of pancreatitis, to be confirmed by integrating clinical signs and ultrasound
Correct. cPLI is the most sensitive and specific serum test available for canine pancreatitis, but no test is perfect: a high value with compatible signs and ultrasound findings (hypoechoic pancreas, hyperechoic mesentery) makes the diagnosis very likely.
D. Amylase and total lipase would have been more specific than cPLI
Amylase and classic total lipase have extrapancreatic sources (intestine, liver) and rise with reduced renal filtration or corticosteroids, so they are much less specific.
lightbulb Key takeaway
cPLI supports a diagnosis of pancreatitis but does not measure severity or replace clinical signs and ultrasound. A normal SNAP cPL makes pancreatitis unlikely; an abnormal one should be quantified with Spec cPL.
