Quick version
If you often experience stomach problems after eating dairy products – such as gas, constipation or a noisy stomach – a lactose intolerance test can provide answers to whether lactose is causing the problems. The test shows whether your body has difficulty breaking down milk sugar, which is often due to a lack of the enzyme lactase.
It is especially relevant to get tested if:
- You suspect that lactose is affecting your stomach
- You want to rule out other causes such as IBS or gluten intolerance
- You want medical confirmation before making dietary changes
- You have relatives with lactose intolerance
A common test is a blood test that analyzes your genetic predisposition to lactose intolerance by examining the lactase gene. This helps to distinguish between genetic intolerance and other causes of stomach problems.
What is a lactose intolerance test?
A lactose intolerance test can help you find out if your body has difficulty breaking down lactose – the milk sugar found in dairy products. This is usually due to a lack of the enzyme lactase, which can be congenital or develop over time.

There are several reasons why it may be a good idea to do a lactose test – here are four:
1. You suspect that lactose affects your stomachDo you often experience stomach problems when you eat dairy products – and can't find any other clear cause? Then a test can help you find out.
2. You want to rule out other diagnosesThere are several different factors that can cause stomach problems, some common examples are IBS, gluten intolerance or other food allergies. A test for lactose intolerance can help you rule out lactose as the cause, and thus facilitate further investigation.
3. You want medical confirmation before changing your dietThere is always a risk of nutritional deficiency with major dietary changes, such as eliminating dairy products, especially if you do not replace them correctly. With a test, you get the facts – and can make the right decision in consultation with a dietitian or doctor.
4. You have relatives with lactose intoleranceSince lactose intolerance is often hereditary, it may be a good idea to get tested if several people in your family have similar problems. This is especially true if you experience diffuse symptoms yourself.
Get answers to whether you are lactose intolerant
A lactose intolerance test based on a venous blood sample analyzes your genetic predisposition to lactose intolerance. By genotyping the lactase gene, the test can identify primary, hereditary lactose intolerance. Read more and order here lactose intolerance test.
