The Newest Way To Meet Your Match: Spitting In A Tube

Yes, you read that correctly. When you friends ask how you met the love of your life, your answer could begin with “Well, I spit in a tube, and…”

It’s probably not the romantic origin story you were expecting, but it’s certainly one of the most high tech. SingldOut.com claims to be the first online dating site to make matches based on your DNA (I don't think it is as the now defunct Scientific Match tried DNA matching back in 2008). The site is partnered with Instant Chemistry, a service that uses psychology and DNA testing to determine "biological compatibility" in a long-term relationship. Here’s how it works:

• Sign up for a SingldOut membership
• Get an Instant Chemistry DNA kit in the mail
• Spit into the enclosed tube
• Pack it up in the included prepaid envelope, then ship it back to Instant Chemistry
• Take a psychological assessment online
• Receive your results, which are posted to your online dating profile, a week later

Instant Chemstiry tests two "markers" in order to determine compatibility. The first is the serotonin uptake transporter, which is involved in how people react to positive and negative emotions. The second are the genes influencing your immune system.

Research shows there is a strong correlation between people in long-term relationships having different (but complementary) versions of the serotonin and immune system genes, but the science is still in its infancy. SingldOut is “looking at a very small number of genes, and you simply cannot extrapolate a prediction from those genes to long-term compatibility," says Mike Dougherty, director of education for the American Society of Human Genetics. It’s impossible to ignore the other genes and environmental factors that come into play during the complex process of attraction.

These days DNA seems to be the pinnacle of science. There are diets designed around your DNA. Crimes are solved via DNA. You can screen for diseases using your DNA. You can learn about your ancestors by your DNA. It’s no surprise that a company is now attempting to bring dating by DNA to the masses, though even they point out that it’s a stretch to consider DNA a top factor in the choice of a partner.

Is it a conceptually interesting prospect? Yes. Is it effective? Perhaps, when used in conjunction with more traditional methods. Is it deterministic? Absolutely not. Not yet anyway , but aren’t you a least a little bit intrigued at the idea of living in a sci-fi future in which we can be matched with perfect partners based on our biology?

Membership to SingldOut is priced at $199 for three months, $249 for six months or $299 for 12 months.
