Chelsea had bloodwork done Thur. and her vet called to say it was
pretty good except for elevated amylase 2424 (300-2000) and a high
band count -13%.
Hi Sandy and Chelsea,
Here is a link that explains the tests for pancreatitis, from
what I have read off other lists the TLI is the confirming test
to have done.
Lipase and amylase are two digestive enzymes produced
by the pancreas that can be measured in the blood.
Elevations in these enzymes can suggest pancreatitis,
but are not definitive tests. This is because both
lipase and amylase are produced by other body tissues,
and because elevated levels may be due to other diseases
such as kidney dysfunction. The lipase test may be more
reliable than the amylase test, but it is not always
available and it must be requested as a special blood
test. Many dogs and cats (15-20%) with pancreatitis do
not have elevations in lipase and amylase, so when these
blood values are normal, it does not rule out pancreatitis.
Trypsin-like immunoreactivity (TLI) test. The TLI test may
help diagnosing acute pancreatitis in both cats and dogs.
This test measures serum concentration of two enzymes,
trypsinogen and trypsin. Trypsinogen is produced only by
the pancreas. With pancreatitis, TLI is elevated more
reliably than lipase. However, reduced kidney function
may cause an increase in serum TLI. Because TLI is not
always elevated, a normal TLI test does not rule out
pancreatitis. Unfortunately, only a few labs perform
this test and it may take about two weeks to get the
test results back.
I hope this helps,
