The term ‘leaky gut’ is used in relation to increased permeability of the intestinal wall and can have several possible causes.

There is no single stool test that can directly establish a ‘leaky gut’. Depending on your symptoms, tests for inflammation, gut flora, infections or other factors may be relevant.

If you are unsure which test is appropriate in your situation, we recommend discussing this with a doctor or another qualified healthcare professional.

Yes. When you place an order, you will receive an invoice by email together with the confirmation.

Your invoice can also be found in your account.

Gut flora

Gut flora testing can also be carried out in babies and young children. A baby’s gut flora differs from that of an adult and develops during the early stages of life.

Gluten test

For testing gluten sensitivity, it is important that gluten-containing products have been consumed during the period before the test. Allow for approximately two months.

Other tests

Many other tests can be carried out at different ages. If in doubt, you can contact us beforehand.

For gut flora testing, it is generally recommended to wait approximately three weeks after a course of antibiotics before sending in a sample.

This gives the gut flora some time to recover after antibiotic use.

For a gut flora analysis, it is recommended to stop using probiotics approximately five days before collecting the sample.

Always follow the instructions supplied specifically with your test.

Acid-suppressing medication can affect the amount of Helicobacter pylori that can be detected.

Therefore, follow the preparation instructions supplied with your test.

Do not stop prescribed medication on your own. If temporarily stopping could cause symptoms, or if you are unsure, discuss this with your doctor or pharmacist first.

According to the standard instructions, you do not need to stop using a laxative for these tests.

If different instructions have been supplied with your specific test, always follow the instructions for that test.

Yes, that is possible.

Try to make sure that the stool sample comes into contact with as little blood as possible.

Various tests, including tests for intestinal parasites, worm infections, histamine intolerance, lactose intolerance and the microbiome, can be returned from Belgium.

For tests that require a fresh stool sample, it is important that the sample reaches its destination as quickly as possible.

Therefore, when sending such shipments from Belgium, preferably use priority shipping. The cost of this international return shipment is at your own expense.

Do you live outside the Netherlands or Belgium? Contact us before sending the sample for the correct return instructions.

It is better not to send fresh samples just before or during the weekend. The same applies to public holidays.

Therefore, preferably collect and send a fresh sample on Monday, Tuesday or Wednesday.

Store the sample according to the supplied instructions until you send it.

For some tests, including certain parasite, histamine, lactose and microbiome tests, material with a stabilising or fixing liquid is used. Different shipping instructions may apply to these.

Therefore, always check the instruction leaflet in your test kit.

If the test requires several samples on different days, follow the instructions supplied with the test kit.

In some cases, you may be advised to collect a sample at a time when symptoms such as urgency or abnormal stools are clearly present.

Always consult the instruction leaflet for your test for the exact collection procedure.

The amount required varies by test.

For a fresh stool sample, the label on the tube indicates how far it should be filled.

For several other tests, only a small amount of material is needed.

The lactose intolerance test is performed using a cheek swab and therefore does not use a stool sample.

Clear collection instructions are supplied with every test kit.

Yes. For example, you can use a clean disposable paper or plastic plate and, if desired, place some clean toilet paper on it.

The most important thing is that the sample is collected dry and clean and does not come into contact with toilet water, cleaning products or other chemicals.

If the tube is too full, this can cause problems during shipping or processing.

Therefore, keep to the fill line on the label.

If you have put too much material in the tube, carefully remove some using the scoop attached to the cap until the material reaches approximately the indicated line.

Then package the sample according to the supplied instructions.

Yes. Loose stool can also be submitted for testing.

Follow the instructions supplied with your test kit regarding the amount and method of collection.

A sample without a fully completed request form may not be processed immediately.

Are your name and other identifying details correctly written on the tube? Contact us as soon as possible so that we can tell you what to do.

If your details are also missing from the sample, always contact us before taking any further steps.

What you should do depends on the type of test.

For certain tests, the sample is stored in a fixing or stabilising liquid. These samples remain suitable for shipping for longer.

For a fresh sample the storage time is more limited. If the sample has been stored for longer, or if shipping would take place just before the weekend, contact us first.

If necessary, we can provide information about requesting new sampling materials.

Have you completed the request form in full, and is there no possibility of confusion between different samples? If in doubt, always contact us before sending the sample.

For most tests, the aim is a processing time of approximately seven to ten working days after the sample has been received.

A microbiome test has a longer processing time. You should generally allow approximately four weeks.

The exact processing time may vary depending on the test and the situation.

However, our customer service does not provide personal medical advice and cannot interpret the content of your results for you.

Do you have questions about the meaning of your results, your symptoms or possible next steps? You can schedule a telephone consultation with a healthcare professional .

For results that may require treatment or additional medical testing, we also recommend discussing the results with your GP or treating physician.

Whether your partner, family members or housemates should be tested depends, among other things, on the parasite found, any symptoms and the individual situation.

Therefore, discuss a positive result with a doctor or qualified healthcare professional. They can assess whether additional testing of other people in the household is appropriate.

After treatment, a follow-up test can be performed in some situations.

The appropriate timing of a follow-up test depends on the parasite found and the treatment you received.

Therefore, discuss with your doctor or healthcare professional when a follow-up test is most appropriate in your situation.

Some parasites can also occur in animals, but this does not automatically mean that your pet is the source of an infection.

You cannot request testing for pets through Darmklachten.nl.

If you have reason to suspect that your pet has a parasitic infection, discuss this with your veterinarian.

Good hand hygiene remains important, especially after contact with animal faeces.
