How It Is Done

An at-home genetic test is a test you do you yourself. You can buy the test at a store or online. The test kit will include instructions on how to do it. But in general:

• You'll collect a sample. This is usually a saliva sample, a swab from inside your cheek, or a blood sample. You might have to go to a local lab to collect a blood sample.
• You'll send your sample to the vendor. Their lab does the genetic testing.
• You'll get the test results back, either online, by mail, or by phone.

Some at-home genetic testing companies may have a genetic counselor or health care provider available who can answer questions or explain results.
