The aminotransfer aspartate test, TGO or AST, is a blood test that is requested to study lesions that compromise normal liver function, such as hepatitis or cirrhosis.
AST is an enzyme present in the liver and normally elevated when liver injury is chronic, located in the liver cell internally. However, this enzyme may also be present in the heart and could be used as a heart marker, which could indicate a heart attack or ischemia.
- As a liver marker.
- AST is usually measured with ALT.
- Which could be elevated in other situations.
- Normal enzyme values are between 5 and 40 U/L of blood.
- Which may vary by lab.
Although the TGO test is not very specific, your doctor may order this test along with others that indicate liver health such as gamma-glutamil-transferase (GGT), alkaline phosphatase (ALK), and mainly ALT/TGP. alt-examination information.
A high TSA may indicate
Values greater than 150 U/L usually lead to liver damage and more than 1000 U/L may indicate hepatitis caused by the use of medications such as acetaminophen or ischemic hepatitis, for example. On the other hand, a decrease in TSA values may indicate vitamin B6 deficiency.
The Ritis relationship is used in medical practice to evaluate the extent of liver injury and therefore establish the best treatment for the situation, this reason is based on AST and ALT values, so that when they are greater than 1, they indicate more serious injuries such as cirrhosis or liver cancer, when less than 1 may indicate that the individual is in the acute phase of viral hepatitis For example.
AST blood test may be requested by your doctor when needed to assess liver health, after finding that the person is overweight, fat in the liver, shows signs and symptoms such as yellow skin color, side pain. abdomen in case of light healing and dark orin.
