Lactose Intolerance Kit FAQ's

Q

What is lactose intolerance?

A

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.

Q

What are the symptoms of lactose intolerance?

A

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.

Q

What should I do if I am lactose intolerant?

A

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.

Q

What is primary lactose intolerance and which other types of lactose intolerance are there?

A

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%. As there are genetic differences between ethnic populations this test is best suited to people of European descent. • 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.

Q

Is lack of the enzyme lactase the same thing as primary lactose intolerance?

A

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 make up 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.

Q

How common is lactose intolerance in the UK?

A

Around 20 % of the UK population is lactose intolerant.

Q

The prevalence of lactose intolerance varies between countries and between different populations. Why?

A

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.

Q

Can you become lactose intolerant later in life?

A

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.

Q

Can you use this test on young children?

A

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.

Q

Can two parents who are not lactose intolerant have a child who is lactose intolerant?

A

Yes

Q

What information is the test providing?

A

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.

Q

Why should I test myself?

A

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.

Q

Are there any risks in connection with taking this test?

A

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.

Q

How accurate is this test?

A

Your sample is analysed in a laboratory and the result is 99,5% accurate.

Q

Who should take this test?

A

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.

Q

How is the sample for the test taken?

A

A simple saliva sample is taken with the special cotton swab provided.

Q

Where can I find the instructions for how to take the sample?

A

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”.

Q

How is the sample sent to the laboratory?

A

Simply remove the parts of the box containing the instructions and the display hook on top of the box by tearing along its perforated edges. To send your sample swab to the laboratory for testing, simply place the box in the addressed Freepost envelope provided and post it to us.

Q

How do I get my result?

A

Your test result can be downloaded from the Dynamic Code website (www.dynamiccode.com/en/receive-your-test-results) using the unique code provided in the kit.

Q

Is everything I need for the test included in the kit?

A

Yes. Everything you need to take the test is included in the kit; instructions, swab, a return envelope and a unique code to get your result from the Dynamic Code website.

Q

What kind of answer do I get after completing the test?

A

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.
