Alpha-1 Antitrypsin (A1AT) Serum Concentration (Qualitative)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have a family history of lung diseases, symptoms like chronic coughing or shortness of breath, or if you have conditions like cirrhosis or liver disease. It may also be used to monitor treatment progress or screen for genetic disorders affecting A1AT production.

What to Expect Before the Test

No special preparation is needed for this test. You may have a small needle inserted into your arm to draw blood. If you’re concerned about needles, let your healthcare provider know. Avoid alcohol for 24 hours before testing if instructed, as it may affect results.

What the Results Mean

Results are qualitative (qualitative means they describe a category rather than a specific number). Low levels of A1AT may indicate an increased risk for lung disease or other health issues. High levels might suggest liver disease or other conditions. Your healthcare provider will interpret the results in the context of your overall health and medical history.

Common Reasons for Testing

This test is often used to diagnose or monitor conditions like Alpha-1 Antitrypsin Deficiency, a genetic disorder that can lead to lung and liver problems. It may also be part of a broader evaluation for chronic lung diseases or to check for liver disease.
