Alpha-1 Antitrypsin Test


Test Description:
The Alpha-1 Antitrypsin test is used to measure the level of alpha-1 antitrypsin (AAT) in the blood. AAT is a protein produced by the liver that helps protect the lungs from damage caused by inflammation and certain enzymes. A deficiency in AAT can lead to an increased risk of lung and liver disease, such as emphysema and cirrhosis. The test helps in the diagnosis of Alpha-1 Antitrypsin Deficiency, an inherited genetic condition that can cause lung and liver damage.

Use of the Test:
The test is used to diagnose Alpha-1 Antitrypsin Deficiency, especially in individuals with a family history of the condition or those who have symptoms of lung or liver disease. It is also used to determine the risk of developing related conditions and to guide treatment decisions.

Patient Preparation/Instructions:
No special preparation is usually needed for the test. However, it is important to inform the healthcare provider about any medications, supplements, or existing health conditions before the test. Patients should also discuss any family history of lung or liver disease with their healthcare provider.

Typical Reference Values:
The typical reference range for AAT levels in the blood is usually between 100 and 200 milligrams per deciliter (mg/dL). Values outside this range may indicate a potential deficiency.

Turnaround Time:
The turnaround time for the test results is typically a few days. However, this may vary depending on the specific laboratory and testing facility.

How to get the Test :
If you have a family history of Alpha-1 Antitrypsin Deficiency or are experiencing symptoms of lung or liver disease, such as chronic cough, shortness of breath, or unexplained liver problems, consider discussing the Alpha-1 Antitrypsin test with your healthcare provider. Early diagnosis and management can help in better understanding and addressing the condition.
