The low-dose dexamethasone suppression (LDDS) test is considered extremely sensitive for hyperadrenocorticism. In approximately 95% of dogs with PDH and up to 100% of dogs with AT, cortisol suppression is inadequate.

testing. Screening tests for HAC include the following: the urinary cortisol:creatinine ratio (UCCR), the low-dose dexamethasone suppression test (LDDST), and ACTH stimulation test. All of these tests have negative and positive attributes; there is no perfect test.5 Any screening test may be negative in a patient with HAC.
The author's preference is to use the ACTH stimulation test as the first screening test and the low-dose dexamethasone suppression test if the ACTH stimulation test gives a normal result in a dog with clinical signs suspicious of hyperadrenocorticism.
Understanding the HRD result. The HRD test result will either show a positive or negative HRD status. A positive status is defined as either the presence of a BRCA mutation or a high genomic instability score.
22 gru 2023 · Understanding your dog’s blood test results is critical for monitoring their health and catching any abnormalities early. Blood tests allow veterinarians to check for signs of infection, anemia, clotting issues, organ problems and more.
The results of a complete blood count include: HCT (hematocrit) measures the percentage of red blood cells to detect anemia and dehydration. Hb and MCHC (hemoglobin and mean corpuscular hemoglobin concentration) measure the oxygen-carrying pigments of red blood cells.
The use of radioactive tags permits the detection of low concentrations of hormones, which typically circulate in the picomolar (10–12) or nanomolar (10–9) range. Nonradioactive tags (eg, chemiluminescence), sandwich-type assays, and ELISA methods have been developed for hormone measurement.
