Searching with DNA

There are three big companies that test and automatically compare results other people in their database. Start with an “autosomal” test. These tests can be used for general search and comparison or to test a specific relationship. If your specific relationship test turns out to be negative, you will still be compared with everyone else in the database both now and in the future. Costs vary but are usually around $100.

23ndMe – This is the most commonly used by Ethiopian adoptive parents to check for siblings and cousins. It’s a spit test and you must use their kit to submit a sample.

Family Tree DNA – this is a cheek swab test. They accept tests without a kit. Call them for instructions on how to submit a sample without a kit.
