Ferrets

Blood biochemistry: alanine aminotransferase

Synonym(s): SGPT, ALT

Contributor(s): Vetstream Ltd, David Perpinan

Overview

  • Released to serum after damage to, or proliferation of, hepatocytes.
  • Heart muscle may have similar ALT activity to liver, although not properly reported in ferrets.
  • Low concentrations of ALT in erythrocytes and skeletal muscle may cause minor ALT increases in hemolytic diseases, muscle wasting, or muscle injury.
  • Elevations, some of them significant and over 1000 IU/L, are commonly seen in ferrets with hepatic disease.
