Test Category
Specimen Requirements
Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)
​Serum ​Red Top Tube (RTT) ​Serum Separator Tube (SST) ​1.0 mL ​400 uL
Collection Processing Instructions
​Samples should be collected from fasting animals: 12-18 hours for non-diabetic animals; 6 hours for diabetic animals.
 
Pancreatic function must be assessed before these results can be interpreted since they may be abnormal in animals with EPI (Exocrine Pancreatic Insufficiency)
 
Serum/Plasma should be separated from cells within one hour of collection.

Test Information

​Reference for TLI is from Gastrointestinal Laboratory - College of Veterinary Medicine Texas A&M University, College Station, TX 77843-4474

Studies show the DGGR lipase correlates well with acute pancreatitis and with the Idexx’s canine Spec cPL lipase assay.
