What is this test?
This test measures the concentration of alpha-aminobutyric acid in serum, the liquid portion of blood. Alpha-aminobutyric acid is an amino acid related to protein and amino acid metabolism. This measurement is considered deprecated and may not be routinely offered by all laboratories.
Why might I need this test?
It may be ordered as part of an evaluation of amino acid metabolism, nutritional status, or a suspected metabolic disorder. Results are generally interpreted together with symptoms, medications, diet, and other laboratory tests.
How is the test performed?
A blood sample is collected, and the serum is analyzed to determine the concentration of alpha-aminobutyric acid. The laboratory may use a specialized method suitable for measuring amino acids.
How do I prepare for the test?
Follow your healthcare professional's preparation instructions. Some amino acid testing may require an overnight fast, so ask whether you should avoid food and beverages for a specific period before the blood draw.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An abnormal alpha-aminobutyric acid level may reflect altered amino acid metabolism, nutritional changes, or impaired liver or kidney function. Certain medications and recent illness can also affect the result. Because this is a deprecated measurement, a healthcare professional should interpret it alongside current laboratory tests and your clinical situation.
Short name
