This test involves blood being drawn, probably from a vein in the patient's elbow.
No special preparations are necessary for this test.
The alanine aminotransferase test (ALT) can reveal liver damage. It is probably the most specific test for liver damage. However, the severity of the liver damage is not necessarily shown by the ALT test.
The patient should keep the wound from the needle puncture covered (with a bandage) until the bleeding stops. Patients should report any unusual symptoms to their physician.
Normal values vary from laboratory to laboratory, and should be available to your physician at the time of the test. An informal survey of some laboratories indicates many laboratories find values from approximately seven to 50 IU/L.
AST is determined by analysis of a blood sample, usually from taken from a venipuncture site at the bend of the elbow
The Aspartate aminotransferase test measures levels of AST, an enzyme released into the blood when certain organs or tissues, particularly the liver and heart, are injured
A red-top tube is typically used for an Aspartate aminotransferase (AST) test, as it allows for serum collection and subsequent analysis.
Liver enzymes in blood tests are ALT/SGPT (alanine aminotransferase) and AST/SGOT (aspartate aminotransferase).
10-40 units/L
The determination of AST levels aids primarily in the diagnosis of liver disease
Elevated levels of ALT and AST in a blood test suggest possible liver damage. ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are enzymes released when the liver is injured. Further evaluation by a healthcare provider is necessary to determine the underlying cause.
Both SGOT (aspartate aminotransferase) and SGPT (alanine aminotransferase) are enzymes found in the liver. They are used as markers to assess liver function and detect liver damage. SGOT is also found in the heart and other organs, while SGPT is more specific to the liver. Generally, elevated levels of these enzymes in the blood indicate liver damage or disease.
