The SneakPeek Early Traits DNA Test Science

How does the SneakPeek Traits test work and is it accurate?

We use a well-recognized method called genotyping to identify small genetic differences that lead to our individual traits. Genotyping has been used to test over 15 million samples worldwide and is scientifically validated to provide accurate and reliable results.

What is the SneakPeek process?

First, we collect the DNA. The At-Home DNA swab kit you’ll receive through the mail has easy instructions to provide a sample – just rub the inside of the cheek with a swab. No blood, no pain, no fuss. When the sample arrives back at SneakPeek Labs, we isolate the DNA and genotype it to identify variants. These variants are used to develop personalized reports, tailored for your unique DNA.

How are the reports developed?

SneakPeek Traits reports are developed by a team of scientists, genetic counselors, bioinformaticians, and data scientists, using the most recent and robust genetic studies. Our nutrition and sleep reports are further refined by experts in the fields to provide tips and advice personalized for your child’s DNA and age.
