Worried about gut symptoms that you think might be related to a parasite, worm or bacteria? Our Comprehensive Gut Parasite, Worm and Bacteria Test Panel detects the most important culprits.
Use our easy home sampling kit to send a stool sample to the lab. Your sample will be analysed by our UKAS-accredited lab partner (who also test for the NHS) and you'll get your results and doctor's report in days.
Depending on your age, sex and any symptoms, you may consider adding to your test panel.
You've got gut symptoms like diarrhoea, stomach pain, nausea and bloating.
You've been travelling abroad.
You've been in contact with someone else with a gut infection or gut symptoms.

Your healthy gut contains trillions of bacteria, parasites, fungi and viruses which usually live in harmony with your body. However, sometimes you can pick up a bug that shouldn't be there and can cause symptoms such as:
You’re more likely to pick up a parasitic or bacterial gut infection while travelling abroad or if someone you spend time with has also been unwell. A lot of the time, gut infections are over in a few days, but symptoms can last longer with gut parasites. If this is the case for you, it can be worth taking a test to see what’s going on.
Our Comprehensive Gut Parasite, Worm and Bacteria Test Panel tests for common and important gut infections caused by bacteria, parasites and worms all from one sample. It combines DNA-based PCR testing and stool microscopy to look directly for worms, parasites and eggs. In particular, PCR is much better at detecting Giardia than microscopy alone.
If your test comes back positive, we'll advise you on the next steps.
It's important to be aware that a stool test is not the best way to pick up pinworms (threadworms). These are tiny, common but harmless thread-like worms that you can sometimes see in stool. If you can see these worms, the recommendation is usually just to treat them with the over-the-counter medication "Ovex" rather than take a test.
It is not uncommon for people to mistake vegetable or other faecal material for a worm. Seeing what you think may be a worm in your stool doesn't guarantee that evidence of a worm (eggs for example) will be seen when the sample is examined under a microscope.
Even when you do have a worm or other parasite infection, there is no guarantee that eggs will be present in the sample that's analysed. It's often recommended to examine up to three separate samples under a microscope to rule out some worm infections.
Bacterial gut infections are often 'short-and-sharp' with violent symptoms that are over in a few days. However, sometimes symptoms can linger and it's worth testing for the commonest bacteria that cause gut infections. We use PCR to test for Salmonella, Shigella, Campylobacter and toxic E. coli (VTEC).
Worms come in a few shapes and sizes. We examine the stool directly and look at it under a microscope to pick up microscopic parasites and any worm eggs. We can see evidence of roundworms, flatworms (flukes) and tapeworms. Sometimes we can also detect threadworms (pinworms) but in general the best way to pick up threadworms is with a swab from the bottom.
Two of the commonest parasites that cause chronic gut symptoms are Cryptosporidia and Giardia. We use PCR testing to pick these up.
Collect your sample at home or visit a clinic.
Use the included envelope to post your sample back to our UKAS-accredited lab (The Doctors Laboratory) for analysis.
We'll deliver your results to your dashboard. Every result is explained so you're in control.
You can also track your results over time.
Our experts will give you a report so you'll know what your results mean.
We'll highlight how you can use your results to understand symptoms, pick up health problems early and take action.
Please get in touch if you have any other questions about our tests.
This easy test checks for the presence of 6 gut parasitic and bacterial infections - Cryptosporidia, Giardia, Salmonella, Shigella, Campylobacter and toxic E. coli (VTEC) - all from a single stool sample. We also check for worms and eggs using stool microscopy. A positive result may indicate that any gut symptoms are caused by an infection that can be treated. A negative result would mean that an infection with one of these bugs or a worm is unlikely.
We do not recommend using this test panel if you:
If you're unsure if you should use this test panel, please contact us for advice.
Your results will be reviewed by one of our doctors. They will write a report explaining what your results mean for you. They will also tell you if there are any specific actions you should take, like seeing a healthcare professional, considering further tests or making changes to your lifestyle.
