ALT and AST what does it mean in cats? - briefly

ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are liver enzymes that are commonly measured in blood tests for cats. Elevated levels of these enzymes can indicate liver damage or disease, such as hepatitis or liver failure.

ALT and AST what does it mean in cats? - in detail

ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are enzymes that play crucial roles in the metabolic processes of cats, as they do in humans and other animals. These enzymes are primarily found in liver cells but can also be present in smaller amounts in other tissues such as heart muscle, kidneys, and skeletal muscles. In cats, ALT and AST levels are often measured to assess the health of the liver, as elevated levels may indicate liver damage or disease.

ALT is commonly referred to as serum glutamic pyruvic transaminase (SGPT), while AST is known as serum glutamic oxaloacetic transaminase (SGOT). Both enzymes are involved in the transfer of amino acids between different compounds within cells. When liver cells are damaged, these enzymes leak into the bloodstream, leading to an increase in their levels.

In cats, AST is more commonly present in various tissues compared to ALT, which makes it less specific for liver disease. However, if both ALT and AST levels are elevated, it may suggest a problem with the liver or other organs that can affect these enzyme levels. It's important to note that other factors such as medications, physical exertion, or certain diseases can also influence ALT and AST levels in cats.

If your cat's veterinarian detects elevated ALT or AST levels during a blood test, they will likely perform additional diagnostic tests to determine the underlying cause. This could include imaging studies like ultrasound or X-rays, as well as further blood work to assess other liver enzymes and indicators of organ function.

In summary, while ALT and AST are essential for normal metabolic processes in cats, their levels can provide valuable information about the health of various organs, particularly the liver. If you have concerns about your cat's health or recent blood test results, it is always best to consult with a veterinarian who can interpret the findings and recommend appropriate care.
