Which is the best vitamin to test for TLI?
Additionally, assays of serum cobalamin (vitamin B12) and folate are strongly recommended whenever serum TLI is assayed. Serum vitamin abnormalities are common in dogs and especially cats with EPI.
When to repeat the TLI assay for epi?
Values between 2.5 and 3.5 µg/L are sometimes (but rarely) associated with clinical signs due to EPI. In these cases the TLI assay should be repeated after one month paying particular attention to ensuring that food is withheld for 8 to 12 hours before the blood sample is collected.
When is trypsin present in the serum TLI?
This assay detects both trypsinogen and trypsin (hence the use of the term TLI to describe the total concentration of these two immunoreactive species), but the active enzyme (trypsin) is only present in the serum when there is pancreatic inflammation.
What should TLI be in dogs for renal failure?
Serum TLI values above 50.0 µg/L (dogs) and 100.0 µg/L (cats) may be associated with either acute or chronic pancreatitis or decreased renal excretion due to severe renal insufficiency, although our experience suggests that serum TLI is often minimally increased even in severe renal failure.
