More about stool tests

Practical information

Frequently asked questions

How does the stool test work from A to Z?

After ordering we ship the kit to your home. You collect a small sample with the included scoop, keep it cool and return it in the envelope. You receive the result digitally by email.

How do I collect a clean sample?

Lay plastic film over the toilet or use a clean container. Scoop from the middle of the stool and avoid contact with urine or toilet water.

How much stool do I need?

A small scoop with the included spoon is enough — about half a teaspoon. More is not better.

How long can I keep the sample before shipping?

Maximum 24 to 48 hours in the fridge. Send as soon as possible and preferably early in the week, not just before the weekend.

Should I avoid medication or food before collection?

Some analyses (like calprotectin) ask you to avoid NSAIDs or certain supplements 24-48 hours before collection. Check the instructions with your kit for the exact preparation for your test.

When and how do I receive my result?

Stool analyses usually take about a week after the lab receives your sample. You receive your laboratory report securely by email. It lists the measured values, units, reference ranges and any flags added by the laboratory.

How do I return the collection materials to the lab?

Use the supplied return envelope and place it in the letter-mail bag inside a PostNL service point yourself as soon as possible. Do not hand it to counter staff or request track & trace. The instructions supplied with your test state when it must be sent.

What if I have questions or something doesn't work?

Feel free to contact us via WhatsApp, email or phone. We're happy to help you before, during or after your test. If the collection doesn't work, we'll arrange a solution or send new materials — no hassle.
