Genetrace Lactose Intolerance Test Overview

Why get tested for lactose intolerance?

Have you recently started experiencing digestive symptoms like gas, bloating or diarrhoea after consuming milk or other dairy-based products? Did you know it is possible to develop lactose intolerance anytime during adulthood?

Almost all of us are born with the ability to break down the milk sugar lactose found in dairy products. Yet quite interestingly, 65% of us (2 out of 3 people) lose this tolerance or the ability to break down lactose as we age. Could your newly acquired digestive symptoms be due to lactose intolerance? The answer to this question depends on your genetics.

Lactose intolerance develops gradually overtime. Digestive symptoms may not be obvious in the beginning. You will first start experiencing bloating and cramping when you drink milk or too many lattes, because milk is high in lactose. Eventually, you may become intolerant to dairy products low in lactose like cheese. Symptoms tend to vary between people, due to variation in enzyme levels.

Do you want to know if you should avoid dairy?

People who continue to enjoy the pleasures of cheese and ice cream carry DNA changes that give them the ability to produce the lactase enzyme necessary to breakdown lactose. This is called “lactase persistence.” In people without the variants, less and less lactase is produced as they age, making it difficult to breakdown milk sugars, which manifests as unpleasant digestive symptoms including bloating, cramps and even diarrhoea.

A lactose intolerance DNA test can tell you conclusively if you carry DNA changes associated with lactase persistence. If you test negative for genetic variants in the MCM6 gene, it means that you are at higher risk of developing lactose intolerance later in life.

Some of the things you can find out from from lactose intolerance DNA testing include:

1. Whether you carry the “lactase persistence” variants that give you the lifelong ability to digest lactose
2. If you do not carry these variants, you are more likely to develop lactose intolerance as you age

What to look for when purchasing a lactose intolerance DNA test

* Laboratory accreditation
* Clinical quality testing
* Repeat confirmation testing for 100% accuracy
* Non-invasive collection
* Turnaround time

DNA Lactose Intolerance Test


The lactose intolerance DNA test that is offered by Genetrace labs is a clinical grade test and will provide you with a comprehensive report on your risk of developing Lactose Intolerance. They use targeted SNP analysis to detect all DNA markers associated with lactose intolerance. The test is performed using a simple cheek swab and can be conducted on individuals at any age. It can be performed at any time, regardless of your current diet. You don’t need to consume diary product before the samples are collected.
