Normal dogs generally have post stimulation cortisol levels > 10 ug/dl. Post stimulation levels < 2 ug/dl is considered diagnostic and most Addison's patients are < 1 ug/dl. The ACTH stimulation test does not distinguish between primary and secondary hypoadrenocorticism, or adrenocortical destruction caused by mitotane overdose.
The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.
Most disease processes cause ALT to rise higher than AST; AST levels double or triple that of ALT are consistent with alcoholic liver disease. [citation needed] When the AST is higher than ALT, a muscle source of these enzymes should be considered. For example, muscle inflammation due to dermatomyositis may cause AST>ALT.
Serum AST level, serum ALT (alanine transaminase) level, and their ratio (AST/ALT ratio) are commonly measured clinically as biomarkers for liver health. The tests are part of blood panels. The half-life of total AST in the circulation approximates 17 hours and, on average, 87 hours for mitochondrial AST. [4]
Cavalier King Charles Spaniel with bandaged foot A dog's injured leg. The health of dogs is a well studied area in veterinary medicine.. Dog health is viewed holistically; it encompasses many different aspects, including disease processes, genetics, and nutritional health, for example.
The tests are different for cats and dogs. In dogs results indicative of pancreatitis may also be caused by renal failure and enteropathies. In cats low sensitivity and other conditions—gastrointestinal diseases, azotemia—that produce similar results mean it is not a useful tool for diagnosis of pancreatitis. [4]
Dog users were very satisfied with their dogs although tests of dogs showed low reliability. [9] The reliability of the dogs ability to detect glycemic levels varies based on the training of the dog along with the breed of the dog for the conditions in which it will be working in. [ 10 ]
Dogs with CPV are at risk of intussusception, a condition where part of the intestine prolapses into another part. [3] Three to four days following infection, the virus is shed in the feces for up to three weeks, and the dog may remain an asymptomatic carrier and shed the virus periodically. [24]
