title: Detecting Alpha-1 Antitrypsin Deficiency.
abstract: Alpha-1 antitrypsin deficiency is a widely underrecognized condition, with evidence of persisting long diagnostic delays and patients' frequent need to see multiple physicians before initial diagnosis. Reasons for underrecognition include inadequate understanding of alpha-1 antitrypsin deficiency by physicians and allied health care providers; failure to implement available, guideline-based practice recommendations; and the belief that effective therapy is unavailable. Multiple studies have described both the results of screening and targeted detection of individuals with alpha-1 antitrypsin deficiency, with both varying strategies employed to identify at-risk individuals and varying results of testing. Also, various strategies to enhance detection of affected individuals have been examined, including use of the electronic medical record to prompt testing and empowerment of allied health providers, especially respiratory therapists, to promote testing for alpha-1 antitrypsin deficiency. Such efforts are likely to enhance detection with the expected result that the harmful effects of delayed diagnosis can be mitigated.
