AST is an enzyme found in the liver, muscles, and other tissues. Birds have naturally higher AST levels than mammals. Normal levels indicate healthy liver and muscle tissue.
Low AST in birds is uncommon and generally not clinically concerning. It may be associated with chronic liver disease in advanced stages or poor nutritional status.
Your veterinarian may correlate this finding with other liver enzymes and overall health.
Avian AST: 85 U/L (Low)AST is an enzyme found in the liver, muscles, and other tissues. Birds have naturally higher AST levels than mammals. Normal levels indicate healthy liver and muscle tissue.
No action needed.
Avian AST: 200 U/LHigh AST can indicate liver damage (hepatitis, fatty liver), muscle injury (capture myopathy, trauma), or noticeable hemolysis. In birds, AST is a more reliable liver indicator than ALT.
Your veterinarian will likely recommend additional liver function tests like bile acids and CK to differentiate liver from muscle origin.
