Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals of any age who are at risk for alpha-1 antitrypsin deficiency due to symptoms or family history.

Probably not a fit

Patients who have already undergone genotype and AAT level testing with a qualified result will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The Alpha-1 Coded Testing (ACT) Study aims to investigate genetic testing and outcomes for individuals at risk of alpha-1 antitrypsin deficiency. This observational study evaluates demographics, reasons for testing, and health outcomes through a confidential testing program that uses coded procedures to ensure privacy. It also explores co-morbidities associated with the condition beyond lung and liver disease. Participants receive their genetic test results by mail, which helps address concerns about genetic confidentiality.

Why it matters

Potential benefit: If successful, this study could lead to earlier diagnosis and better management of alpha-1 antitrypsin deficiency.

How similar studies have gone: Other studies have shown success in genetic testing approaches for similar conditions, indicating a promising avenue for this research.
