DNA tests can now be used to locate relatives and genetic cousins--people who share a common ancestor with you--anywhere in the world. Companies such as Family Tree DNA and Igenea sell DNA test kits for the public, and compare clients' test results against their own vast DNA databases. For example, the Family Finder Test, offered through Family Tree DNA, uses autosomal DNA--found on non-sex chromosomes--to search for family across all your genetic lines, up to six generations back.
Step 1
Order a DNA test kit from the DNA testing company of your choice. Make sure you order a kit for the test that will search for relatives--those who share a common ancestor with you from the last four to 40 generations. These people can be from anywhere--Igenea's DNA database, for instance, lists a quarter of a million people from 98 countries as of 2010.
Step 2
Wash your hands and carefully remove the mucus sample test kit from the DNA test kit.
Step 3
Take a mucus sample from whomever you are testing--yourself or others members of your immediate family--by swabbing the inside of the cheek and placing the used swab in the container provided. Ensure you only use one sample per swab, as the genetic material must remain isolated for the test to work.
Step 4
Sign the release form and return the mucus sample to the company. The release form is important: without it the company will not be able to share your name and email address with the relatives that your search produces. Allow 6 to 8 weeks for the company to process your results.
Step 5
Opt in to the company's DNA database while you are awaiting your results. Like the release form, this step allows you and your familial matches to become aware of and contact each other.
Step 6
Receive your results and contact your relatives and genetic cousins via email. You will only be able to contact other customers who make themselves available in the DNA database to match.
Tips and Warnings
- Get clear on the question you have of your genes, because the question will determine the type of kit you buy. What do you want to find? If you are looking for family, a test that searches for relatives is all you need. If you are interested in finding family as well as answers about your ancestry--maybe to discover if a family legend is true, for example, or if you are part Irish--you will need different types of tests. The more specific you can be with your question, the easier it will be to locate the right product.
- Compare prices between several DNA testing companies, and carefully read the details of each test. If you are not sure what you are buying, don't buy it. These tests can quickly become expensive, so ask questions and do your due diligence before you invest your money.
