α1-antitrypsin deficiency (AATD) remains the only readily identified genetic cause of chronic obstructive pulmonary disease (COPD). Furthermore, there is growing evidence that even a moderate deficiency increases the risk of lung disease among smokers. Despite these facts, the uptake of testing for AATD in at-risk populations remains low for many reasons, and a lack of clarity among clinicians regarding the most appropriate diagnostic techniques presents a major deterrent. This Personal View addresses the benefits of diagnosis, the technical basis of the available diagnostic methods, and possible clinical confounders for each test. We include a series of unusual cases encountered at our National Centre of Expertise to provide context. The topics covered should equip clinicians with the core knowledge required to confidently assess patients for AATD.
