Screening tests

Timing is important

Cortisol screening tests

The need to test for under function (Addison's disease) or over function (Cushing's disease) of the adrenal glands is common in the older dog. These tests take time
There are 2 main screening tests performed at Seaforth vets, both for the detection and monitoring of Cushing's and Addison's Disease

ACTH Stimulation

This takes 1 hour only. So it can be performed any time of day up to 5pm say. Animal need to be dropped off at the hospital. However it is best not to feed them 12 hours before any blood testing so morning is easiest on the animal. For diagnosis it can be performed at any time of day

Trilostane Efficacy

When we wish to assess the efficacy of Trilostane, the ACTH stim. test is optimally run 4 hours after the morning dose of trilostane. eg morning dose at 6am then ACTH stim. test at 10am

Dexamethasone Screening

This takes 8 hours, so the animal MUST be dropped off by 10 am at latest to fit the test into the day. Again starve over night for best results
