Alpha-1 Antitrypsin (Serum) Concentration

Why It Matters in Your Health

Alpha-1 Antitrypsin plays a critical role in preventing lung tissue damage. Low levels can increase your risk of developing chronic obstructive pulmonary disease (COPD) or liver diseases, particularly if you have a genetic predisposition. This test is often used to diagnose or monitor these conditions in people with a family history of lung disease or liver problems.

What to Expect During the Test

A simple blood sample is drawn from a vein, usually in your arm. The blood is sent to a lab for analysis. You may feel a slight pinch, but the process is quick and typically doesn’t require any special preparation.

Possible Causes for Testing

Your healthcare provider may recommend this test if you have symptoms like chronic cough, shortness of breath, or liver issues. It’s also used in screening for genetic conditions linked to A1AT deficiency, especially if you have a family history of lung or liver diseases.

What the Results Mean

Results are compared to a standard range to determine if your levels are low, normal, or high. Very low levels may indicate a genetic disorder, while very high levels might suggest liver disease or other conditions. Your doctor will interpret the results in the context of your overall health and symptoms.
