Health Problems That Can Cause AST Levels To Be Elevated In Your Pet’s Blood :

All infectious, toxic, metabolic and cancerous diseases that can affect your dog or cat’s liver can cause your pet's AST blood levels to rise.

When ALT levels in the same blood sample are normal, red blood cell destruction are common causes for high AST readings. Muscle damage due to severe exertion or trauma and congestive heart failure can also be responsible for elevated AST reading in dogs and cats.

AST levels go up occasionally as the result of local reaction to vaccinations and intra muscular injections of all kinds.

AST levels are often increased during heartworm treatment with Immiticide.

Hemolized blood samples can also cause falsely high AST readings.

Health Problems That Can Cause AST Levels To Be Low :

Flagyl (metronidazole) has been known to cause low AST readings, as has a vitamin B6 deficiency.

Complementary tests :

ALT, bilirubin, bile acids, Hct, SDH, CK , TP & Gamma Globulin elevation as evidence of FIP in cats, abdominal ultrasound, retest dogs in 2 days , cats in 1.
