Specimen Type: Blood
Alpha 1 Antitrypsin (A1At) Blood Test (Labcorp)
This test measures the level of Alpha-1 Antitrypsin in the blood. A1 antitrypsin is a protein that helps to break down enzymes produced by the immune system which would otherwise be damaging to tissues in the lungs. People with an A1 antitrypsin deficiency have a higher risk of developing chronic obstructive pulmonary disease (COPD) including emphysema and bronchitis. A1at deficiency can also cause an increased risk of developing liver disease, cirrhosis, and liver cancer. Measuring A1at levels can help to determine the cause of a person's illness or differentiate it from other conditions.
An A1 antitrypsin test is often ordered when someone has symptoms of emphysema such as wheezing, chronic cough, or shortness of breath. It can also be used to aid in diagnosing the cause of unexplained illnesses such as bronchitis, asthma, and liver disease. A1at deficiency can be an inherited disorder so testing is often recommended for someone with a family history of lung or liver disease.
Turnaround for this test is typically 1-3 business days.
