Low Dose Dexamethasone
Suppression Test
Protocol Instructions
Why does my dog need this test?
The low dose dexamethasone suppression test (LDDST) is routinely
used in the diagnosis of dogs with hyperadrenocorticism (HAC),
sometimes referred to as Cushing’s syndrome.
This test measures
the response of the pituitary gland to a small dose of
dexamethasone.
Although your veterinarian may suspect HAC
based on your dog’s history and physical examination, tests to
confirm the diagnosis are required before treatment can be started.
What does this test involve?
There are four parts to this test.
First, a blood sample is collected
from your dog.
A small dose of a steroid called dexamethasone is
then injected, usually into the vein on the fore leg.
Blood samples
are then collected 4 and 8 hours later.
The test is not particularly
painful or stressful for your dog.
