The first-ever device for consumers to screen for alpha-1 antitrypsin deficiency (AATD) will be available for adults in the United States in the second quarter of 2023.

AATD significantly increases the risk of chronic obstructive pulmonary disease, a condition that approximately 16 million Americans have but many more are suspected to be undiagnosed. In fact, over 90% of AATD cases are thought to be undiagnosed, therefore, this direct-to-consumer product will be of significant diagnostic value to patients and healthcare providers. No prescription is needed.

The easy-to-use test screens for the most common genetic mutations associated with AATD, including rare and null alleles, as well as the S, Z, F, and I alleles. Users simply collect a saliva sample, send it to a laboratory for processing, and they will receive a report via a secure online portal within a few weeks.

A study on the ease of comprehension of the reports generated by AlphaID showed a 90% or greater level of understanding among a broad US demographic. Patients are encouraged to share the test results with their physician and discuss possible therapeutic options.
