About this test

Concerned that your digestive problems might stem from lactose intolerance? Discover if you could be among the nearly 65% of people worldwide with some degree of lactose intolerance through the DNA Lactose Intolerance test. This test includes an analysis of five common genetic variants in the MCM6 gene, allowing it to distinguish between lactose intolerance and lactase persistence.


Lactose intolerance and lactase persistence represent opposite conditions in the context of milk sugar digestion. Those who are lactose intolerant have difficulty digesting and absorbing lactose, the sugar found in milk, due to low levels of the lactase enzyme. This often leads to digestive symptoms such as gas, bloating, and diarrhea upon consuming dairy products.

On the other hand, lactase persistence is characterized by the continued production of the lactase enzyme throughout one’s life, allowing individuals to digest lactose effectively even into adulthood.

To assess whether you may be at an increased risk of lactose intolerance, a straightforward DNA analysis is conducted using a simple mouth swab.

Technical Info

The most influential factor in predicting lactose intolerance and lactase persistence is genetic variation. Through this DNA test, we ascertain whether you have inherited any of the five common changes in the MCM6 gene, which play a key role in enabling lactase persistence.

The MCM6 gene is responsible for encoding a protein that regulates the production of various proteins, including lactase, which is encoded by the nearby LCT gene. Individuals with at least one of the specific variants in these genes are less likely to experience lactose intolerance. Conversely, those lacking any of these variants are at an elevated risk of developing lactose intolerance.
