Further study details as provided by Medical University of South Carolina:

Primary Outcome Measures:

Structured questionnaire responses on the risks and benefits of testing. [ Time Frame: Before and after alpha-1 antitrypsin testing ] [ Designated as safety issue: No ]
Rotating questionnaires assess the clinical course and co-morbidities associated with different genotypes of alpha-1 antitrypsin deficiency.

Estimated Enrollment:	50000
Study Start Date:	January 2001
Estimated Study Completion Date:	January 2050
Estimated Primary Completion Date:	January 2050 (Final data collection date for primary outcome measure)

Intervention Details:

Home fingerstick testing for alpha-1 antitrypsin genotype

Detailed Description:

Genetic testing for alpha-1 antitrypsin deficiency is sometimes delayed despite established testing indications. All genetic tests have risks and possible benefits. The ACT study evaluates the population demographics, reasons for testing, and outcomes through a confidential testing program. Co-morbidities of alpha-1 antitrypsin deficiency other than lung and liver disease are being investigated. Concerns about genetic confidentiality are lessened in this study by a coded testing procedure that returns results through the mail to study participants.
