SNAP® cPL Test

(canine pancreas-specific lipase)

For a more complete diagnostic picture


When dogs present with vomiting, anorexia or abdominal pain, the culprit could be pancreatitis. The SNAP® cPL™ Test is the only pet-side test developed to measure canine lipase levels specific to the pancreas.

Diagnose or help rule out pancreatitis with the SNAP cPL Test:

  • The most accurate pet-side canine pancreatitis test available
  • More specific than serum lipase testing for diagnosis of acute pancreatitis
  • Results in just 10 minutes for answers during the patient visit

Pet-side screening you don't have to second guess
Can be used on the SNAPshot Dx® Analyser! 

Know more about your patients sooner with the SNAP® cPL Test.

Improve your ability to diagnose canine pancreatitis sooner:

  • Use the only pet-side test that measures canine lipase levels specific to the pancreas
  • Include with initial workup to identify pancreatitis before it becomes more serious
  • Provide answers and treatment plans during the patient visit with 10-minute results

Accurate and easy to read:

  • Provides a “normal” or “abnormal” result for pancreatic lipase levels in just 10 minutes
  • In a study involving veterinary technicians, 96% of the results were correctly interpreted
  • Automatically record results when used with the SNAPshot Dx® Analyser

Accuracy of the SNAP® cPL Test

Repeatability (Qualitative Precision)
Repeatability studies were conducted by running multiple replicates of five canine serum pools on SNAP cPL devices. The canine pancreatic-specific lipase (cPL) concentration of each canine serum pool was measured using the Spec cPL assay. SNAP cPL devices were run and visually interpreted by a single operator and results were tabulated as either N (Normal) or A (Abnormal). Within-Day and Day-to-Day repeatability were determined by running n=10 replicates per pool over three days. The results of this study are guidelines.

SNAP cPL test sensitivity and specificity

Agreement with Spec cPL® Reference Method

A user group study was conducted to evaluate agreement between SNAP cPL visual results and Spec cPL quantitative results.

  • Study Design:
  • Twenty canine serum samples with known Spec cPL concentrations were assayed on SNAP cPL devices.
  • Each device was visually interpreted twice by each of 14 veterinary professionals for a total of 28 observations per sample. (Total n=560)
  • Veterinary professionals were blinded as to the Spec cPL concentrations of the samples.

96% (536) of the interpretations were correct.

Statistical significance:
With 95% confidence, there is 94.0–97.4% agreement between the SNAP cPL and Spec cPL methods.

Resources and support materials for the SNAP® cPL Test

It's easy to use the SNAP® cPL™ Test:


Dispense 3 drops of sample and 4 drops of conjugate into a disposable sample tube.
Gently invert the sample tube 4–5 times to mix.
Pour the entire contents of the sample tube into the sample well of a SNAP® device.


When colour first appears in the activation circle, press firmly to activate. You will hear a distinct “snap.”
Read the test result 10 minutes from the time of activation.


View the package insert (PDF) for detailed instructions.


Sample Information

  • Samples must be at room temperature (15°–25°C) before beginning the test procedure.
  • Serum, either fresh or stored at 2°–8°C for up to one week, can be used.
  • For longer storage, serum can be frozen (-20°C or colder) and then recentrifuged before use.
  • Haemolysed, icteric or lipaemic samples will not affect results.


Interpreting Results

Interpreting SNAP cPL test results



SNAP cPL Normal

Normal Level
If the colour intensity of the sample spot is lighter than the colour intensity of the reference spot, cPL levels are normal.
Note: It is possible for no colour to develop on the sample spot.

SNAP cPL Abnormal

Abnormal Level
If the colour intensity of the sample spot is equal to or darker than the colour intensity of the reference spot, cPL levels are abnormal.

Invalid Results

  • Background—If the sample is allowed to flow past the activation circle, background colour may result. Some background colour is normal. However, if coloured background obscures test result, repeat the test.
  • No Colour Development—If reference spot does not develop colour, repeat the test.
