What you get with this test
Detailed Description
Lactose Intolerance vs Lactase Persistence
People who are lactose intolerant cannot digest and absorb the milk sugar lactose, because they produce only low levels of the lactase enzyme. This causes digestive symptoms like gas, bloating and diarrhea, when dairy products are consumed.
Lactase persistence is the opposite of lactose intolerance. People who are lactase persistent are able to produce the lactase enzyme for their entire lives, meaning they can continue to consume dairy products right through adulthood.
A simple mouth swab is all we need to analyze your DNA and determine whether you are at increased risk of lactose intolerance.
The Genetics
Genetic variation is the strongest predictor of lactose intolerance and lactase persistence. This DNA test determines whether you have inherited any of the five common changes in the MCM6 gene that enable lactase persistence.

How Common is Lactose Intolerance?
The likelihood of lactose intolerance depends on ethnicity. Lactose intolerance is the normal phenotype. The mutations associated with lactase persistence occurred, and were selected for, when there was an increased reliance on dairy as a food source.
Many ethnicities are mostly lactose intolerant, including 90% of Asian Americans, 70% of African-Americans, 95-100% of Native Americans and 50% of Mexican-Americans.
In contrast, less than 25% of Caucasians and only about 5% of people of Northern European ancestry are lactose intolerant, because dairy has been a food staple in their past.
