The U.S. Department of Homeland Security will start using Rapid DNA tests on some asylum seekers at the U.S.–Mexico border next week, according to a new report from CNN. The tests are intended to determine whether adults and children who are traveling together are actually family members.
The Rapid DNA tests involve a cheek swab and will be deployed at two ports of entry starting the week of May 6. Results from the test take about 90 minutes.
These new Rapid DNA tests are supposed to catch immigrants who are lying about being related, but it’s unclear how DHS can establish familial ties through DNA alone. Obviously, DNA relations aren’t the only thing that define a family.
