Performing Lab
Alpha‑1‑Antitrypsin Quantitative
Clinical Use
Order TestUse
This test quantitatively measures the concentration of alpha‑1‑antitrypsin (AAT) in serum for evaluation of risk or diagnosis of alpha‑1‑antitrypsin deficiency, which may predispose to emphysema and/or liver dysfunction. Low circulating levels of AAT suggest potential deficiency states that warrant clinical attention.
