AncestryDNA, the most popular company, says it sold 1.6 million kits over the four-day Black Friday to Cyber Monday weekend last year.
In a statement to WFXT, an AncestryDNA spokesperson said their information security program is designed to protect customer data, and said they don't share customer DNA with insurers, employers or third-party marketers.
Time magazine put out a list of five things people should know when buying a consumer kit:
1. You won't find out everything about your genes.
2. Don't expect to learn if you're going to get cancer.
3. You'll learn more about where you came from.
4. Your DNA may not be as private as you think.
5. Your DNA isn't your destiny
"Certainly, your genes are not your destiny," Abbott said. "There's a lot of things who influence who we are and our health, and who we're gonna be."
Companies like Orig3n, which makes a child development DNA test, claim to test whether your child has a predisposition for certain sports, is a picky eater, or can easily learn new languages.
Child psychologists say results from tests like these could affect how parents would have otherwise raised their children.
"In general, we discourage genetic testing of children," Abbott said. "It's not particularly helpful in terms of taking care of them. I think, in terms of directed consumer genetic testing, this is for adults only."
AncesterDNA said they will also not share customer personal information with law enforcement unless compelled to by a valid legal process.
Abbott said the bottom line is, if someone wants to test their DNA for fun, they can go for it. But, if they're looking to do it for any other reason, they should get help from a professional.
