Frequently Asked Questions

This test will reveal your genetic likelihood of being lactose intolerant. By analyzing the MCM6 gene, it determines your body’s ability to produce the lactase enzyme, which is necessary for digesting lactose, the sugar found in dairy products.

If you experience symptoms like gas, bloating, stomach cramps, or diarrhea after consuming dairy, this test can provide valuable insight. It is also suitable for anyone who is simply curious about their genetic predisposition to lactose intolerance.

Lactase production naturally decreases after infancy for most people. However, some people have a genetic variant in the MCM6 gene that allows them to continue producing lactase throughout their adult life, a trait called lactase persistence. If you have two copies of the “normal” gene without this variant, you are genetically predisposed to be lactose intolerant in adulthood.

Your results will tell you which copies of the MCM6 gene you have inherited. The report will indicate if you have two copies of the normal gene (likely lactose intolerant), two copies of the variant gene (likely to have lactase persistence and tolerate dairy), or one of each (typically have lactase persistence, though some sensitivity is possible).

This test identifies the genetic markers associated with lactose intolerance, providing a strong indication of your predisposition. However, for a formal medical diagnosis, it is always best to consult with your healthcare provider to discuss your results and symptoms.

Lactose intolerance is a digestive issue caused by the inability to break down lactose, the sugar in milk. A dairy allergy is an immune system reaction to the proteins in milk. This test specifically looks at the genetic markers for lactose intolerance.
