Definitively diagnosing canine hyperadrenocorticism (Cushing's disease) can be exceptionally difficult because nonadrenal illness can affect the test results. However, I think that the urine cortisol:creatinine ratio (UC:Cr) serves an invaluable role in ruling out canine Cushing's disease since a dog with a normal UC:Cr almost assuredly does not have Cushing's disease.
Failure to use best-practice techniques, such as centrifugation, when conducting fecal flotation procedures can result in failure to detect parasite stages in fecal samples. In this article, we review the basics of fecal flotation techniques and describe step-by-step procedures for conducting accurate and effective centrifugal flotation procedures.
This review provides general guidelines for the diagnostic approach to an asymptomatic dog with elevated liver enzyme activities so that needless tests are not performed and clinically important liver disease is not missed.
You may be hesitant to perform a full-thickness incisional biopsy to obtain an intestinal tissue sample, but in many cases, this technique is preferred. In this article, we review when incisional biopsy is best and provide a simple step-by-step guide to the procedure to increase your confidence.
A 15-year-old 15.1-lb (6.9-kg) castrated male Lhasa Apso was presented to the Veterinary Medical Teaching Hospital at Texas A&M University for evaluation of chronic vomiting of several months' duration.
Dogs and cats with pancreatitis commonly display nonspecific clinical signs, so the condition can be difficult to diagnose. But there also has been a lack of diagnostic tests for pancreatitis that are both sensitive and specific. In this article, I provide an overview of the available diagnostic tests, including a new serum test.
Indications for electrocardiography include arrhythmias heard on auscultation, breathing problems, shock, fainting or seizures, cardiac murmurs, and systemic disease that affects the heart (e.g. tumors, kidney dysfunction, heartworm disease).
