Lactose Intolerance Kit
A home diagnostic test to confirm Lactose Intolerance using laboratory DNA testing
Our Lactose Intolerance DNA kit is the first home test available on the market to confirm if you have primary lactose intolerance, with an accuracy of 99.5%. Lactose Intolerance is an inherited condition, where the amount of the enzyme lactase that your body produces starts to fall, usually from the age of 3 years onwards. The symptoms of the condition develop over time and vary from one person to the next so it is very difficult to diagnose without a test.
If you suspect you are lactose intolerant, why not take our easy-to-use test and be certain! The test is very easy to perform. Simply take a saliva sample using the swab provided in the kit and send it to our accredited laboratory for analysis. The DNA in your saliva sample will be analysed for a genetic predisposition to lactose intolerance and your results can be downloaded from the website using a unique code provided in the kit within 5 days from the arrival of the sample at the laboratory.
Everything you need for the test is included in the kit, including easy to follow instructions, and swab.
To take the test simply:
- Rinse your mouth with water
- Open the box, which contains a cotton swab in a test tube, zip-bag and an instruction leaflet. Carefully tear off the analysis code from the test tube and keep it safe. Unscrew the cork on the test tube and pull out the cotton swab.
- Rub the cotton end of the swab against the inside of your cheek for 3 -4 seconds.
- Place the cotton swab in the test tube, place the tube in the zip-bag and then into the kit box and lock it. The box is now ready to be used as the return package. Send the prepaid shipment by post.
Results are provided within 5 working days after the sample is received at the laboratory. You can check the status of your test and obtain your test results, using the website address and your test's unique code number provided with the test.
PLEASE NOTE! Due to difficulties caused by current healthcare crisis and changes after the end of Brexit transition period test results availability may be delayed. We appreciate your patience and understanding.
About Lactose Intolerance
Lactose intolerance is a common problem of the digestive system that is caused by lack of the enzyme lactase, which is used to break down lactose, a natural sugar found in the milk of mammals, including cows, goats, and sheep. Foods that contain lactose include:
- dairy products such as cream, cheese and yoghurt
- biscuits and chocolate
- some breakfast cereals
Symptoms of Lactose Intolerance
Lactose intolerance occurs when the body cannot break down and absorb lactose. It is usually caused by a lack of the enzyme lactase, which is produced by the small intestine. If there is not enough lactase in the small intestine, the lactose cannot be digested and it passes intact into the lower intestine, where it is fermented by bacteria and gives rise to abdominal symptoms such as:
- a bloated stomach
- flatulence (wind)
- frequent diarrhoea
- stomach pains and rumbling
- stomach cramps
The symptoms of lactose intolerance can be very similar to those of other conditions, such as irritable bowel syndrome (IBS) or milk protein intolerance. IBS is a chronic (long-term) disorder that affects the digestive system. Milk protein intolerance is an adverse reaction to the protein in milk from cows, but it does not involve the immune system (milk allergy). Due to the similarities of these conditions, they can easily be confused and so testing for Lactose Intolerance is particularly advantageous in ruling the condition in or out and enabling you to make appropriate changes to your diet.
Types of Lactose Intolerance
There are three different types of lactose intolerance. By far the most common is Primary lactose intolerance, an inherited condition where the production of lactase in the body usually starts to fall from the age of 3 years onwards. The symptoms of lactose intolerance develop over time and will vary from one individual to the next. Primary lactose intolerance is very common and found in approximately 5% of adults in the UK. In some ethnic populations it is even more common, particularly those where milk is not traditionally included in their diet. These include people of Hispanic, south Indian, American Indian and black or Ashkenazi Jewish origin, where lactose intolerance can occur in up to 50-80% of adults.
The other types of Lactose Intolerance are uncommon. Secondary lactose intolerance can occur as a side effect of other intestinal diseases, such as coeliac disease and is often temporary. Congenital lactase deficiency is a very rare genetic disorder present at birth. Our Lactose Intolerance kit confirms if you have the inherited Primary Lactose Intolerance from your DNA and cannot be used to identify the secondary or congenital forms.
Living with Lactose Intolerance
Lactose intolerance cannot be prevented or cured, as it is a genetic trait that you inherit. However if have taken a test such as our Lactose Intolerance DNA test and you know for certain that you are lactose intolerant it can normally be controlled by making appropriate changes to your diet. By only eating or drinking dairy products that are within your body’s tolerance levels, or by choosing products with low levels of lactose, the symptoms can be controlled. Lactose intolerance can range from mild to severe, depending on how much lactose a person has in their diet and how well their body can digest it. The amount of lactose that it takes to start your symptoms will vary from person to person. In more severe cases, supplementary lactase enzyme can also be ingested with the food to make the lactose more digestible, on the advice of your dietician or doctor.
Lactose Intolerance Kit – Frequently Asked Questions
What is lactose intolerance?
Lactose intolerance is a common problem of the digestive system caused by the lack of the enzyme lactase. The absence of lactase means that lactose (milk sugar) is not digested in the small intestine and it passes intact into the colon. If there is not enough lactase in the small intestine, the lactose cannot be digested and it passes intact into the lower intestine, where it is fermented by bacteria. This can cause abdominal symptoms such as stomach pain, bloating, flatulence and diarrhoea. Lactose is found primarily in dairy products, but also as an additive in other food products, such as some chips and powdered products.
What are the symptoms of lactose intolerance?
Lactose intolerance causes abdominal symptoms such as stomach pain, bloating, flatulence and diarrhoea. The symptoms may vary from person to person. Some people tolerate dairy products in small quantities and others not at all.
What should I do if I am lactose intolerant?
If you are lactose intolerant, you can control your symptoms by making appropriate changes to your diet. By only eating or drinking dairy products that are within your body’s tolerance levels, or by choosing products with low levels of lactose, the symptoms can be controlled. If you prefer professional help or advice, you can contact your Doctor or a dietician.
What is primary lactose intolerance and what are the other types of lactose intolerance?
There are three types of lactose intolerance. • Primary lactose intolerance is the most common type of lactose intolerance. It is an inherited condition and genetically based. The production of lactase in the body usually starts to decrease at the age of 3 years. The symptoms develop over time and will vary from person to person. This test shows if you have this type of lactose intolerance with an accuracy of 99.5%. • The second type is secondary lactose intolerance. This type can occur as a side effect of other intestinal diseases, such as coeliac disease and is often temporary. • The third type is congenital lactase deficiency, a very rare genetic disorder present at birth.
Is lack of the enzyme lactase the same thing as primary lactose intolerance?
Primary lactose intolerance is a condition caused by the lack of the enzyme lactase. There is considerable variation between individual’s Lactase levels and this will determine the severity of the symptoms and the person’s tolerance of lactose. In addition, the makeup of each person’s gut bacteria also has an impact on the severity of the symptoms. So the two terms ‘primary lactose intolerance’ and ‘primary lack of lactase’ are often used to describe the same thing.
How common is lactose intolerance in the UK?
Around 20 % of the UK population is lactose intolerant.
The prevalence of lactose intolerance varies between countries and between different populations. Why?
Primary lactose intolerance is an inherited condition that is genetically based. Lactose intolerance was the normal condition in our ancestors, but over time and an extensive Western cultural history of using dairy products successive generations have passed on gene mutations that maintained the lactase activity into adulthood.
Can you become lactose intolerant later in life?
Yes. You can have the genetic disposition for primary lactose intolerance, but the age when the symptoms develop will vary from one person to the next.
Can you use this test on young children?
This is not recommended, as young children have normally not yet developed the symptoms of primary lactose intolerance. Since the test shows the genetic disposition for primary lactose intolerance, you can use the test on smaller children in order to get information about possible future problems arising from primary lactose intolerance. The symptoms of primary lactose intolerance normally start to show by the early teens, but there are significant individual variations.
Can two parents who are not lactose intolerant have a child who is lactose intolerant?
What information is the test providing?
The test is a DNA-test showing if you have the genetic trait associated with primary lactose intolerance, which is the most common type of lactose intolerance.
Why should I test myself?
This simple and safe DNA test shows if you have the genetic trait that is associated with primary lactose intolerance. With this test you can find out whether you abdominal symptoms could be due to primary lactose intolerance and that you could control by making appropriate changes to your diet. These could include adjusting your intake of dairy products in line with your body’s tolerance levels, or by choosing products with low levels of lactose.
Are there any risks in connection with taking this test?
No, if you follow the simple instructions there is no risk what so ever. You should be aware that stomach problems may be due to a number of reasons, and that even if your test result shows you are primary lactose intolerant, if the problems remain after you adopt a lactose free diet, you should contact your doctor for further advice. Please note that young children very seldom suffer from primary lactose intolerance. Normally primary lactose intolerance only starts to show in the early teenage years, but there are individual variations.
How accurate is this test?
Your sample is analysed in a laboratory and the result is 99,5% accurate.
Who should take this test?
People with stomach problems that could be due to lactose intolerance, including pain, bloating, flatulence or diarrhoea. As there are genetic differences between ethnic populations this test is best suited to people of European descent.
How is the sample for the test taken?
A simple saliva sample is taken with the special cotton swab provided.
Where can I find the instructions for how to take the sample?
You will find the instructions on the tab surrounding the box. Open the tab on the side of the box on which are printed; “instructions open here”.
How is the sample sent to the laboratory?
Simply put the sample in the box and post the box which has the pre-paid postage printed on.

Is everything I need for the test included in the kit?
Yes. Everything you need to take the test is included in the kit; instructions, test tube with the swab, and a unique code to get your result from the Dynamic Code website.
What kind of answer do I get after completing the test?
Your answer will show if you are carrying the genetic trait associated with primary lactose intolerance. If you are lactose intolerant, you can control your symptoms by making appropriate changes to your diet. By only eating or drinking dairy products that are within your body’s tolerance levels, or by choosing products with low levels of lactose, the symptoms can be controlled. If you prefer professional help or advice, you can contact your doctor or a dietician.
