Alpha-1 Antitrypsin (AAT)
Item Catalog Number: LC001982
This test is used to detect hereditary decreases in the production of alpha-1 antitrypsin (AAT). AAT is responsible for inactivating endoproteases (protein catabolic enzymes). Decreased or nearly absent levels of AAT can be a factor in chronic obstructive lung disease and liver disease. Elevated levels can also be an indication of inflammatory states (eg, rheumatoid arthritis, bacterial infection, vasculitis, neoplasia).
An 8-12-hour fast is required for this blood test. However, drink plenty of water and take your medications as prescribed.
