Travellers' Diarrhoea GI Panel PCR Test
Returning from your travels with a stomach bug?
Still experiencing Travellers' Diarrhoea symptoms weeks after returning home?
If you have persistent diarrhoea symptoms on return from your travels, we can help – with fast, accurate diagnosis to pinpoint the cause, and with prompt treatment from our Travel Medicine specialists.
Our Gastrointestinal (GI) Panel PCR stool test looks for any microbes that may be causing your symptoms and can quickly identify the exact cause of your Travellers’ Diarrhoea. Results can be provided in as little as one hour, so that accurate and effective treatment can begin straight away.
Viruses, bacteria or parasites can all cause similar symptoms but require an entirely different treatment approach. If your Travellers’ Diarrhoea has a viral or parasitic cause, antibiotics will not help.
Pinpointing the exact cause – rather than just making an educated guess – is the key to successful treatment, especially if a first attempt at treatment has already failed.
Our “gastrointestinal panel” is capable of detecting any of the 23 commonest pathogens that cause diarrhoea – such as E. coli, campylobacter, norovirus salmonella, shigella and giardia, from a single stool sample – all that’s needed is a simple swab.
Traditional lab tests such as microscopy and culture can take days to yield useful results. By contrast, PCR allows detection of the tiniest traces of genetic material from the viruses, bacteria, and parasites that cause infection.
Because our laboratory is situated within our own clinic, we can run samples immediately, and provide test results in little over an hour. This means that treatment can start confidently and correctly, right way. With growing concerns about antibiotic resistance, it also means that antibiotics can be confidently avoided when they are not needed.
As one of the leading independent specialist travel clinics in the UK, we look after large numbers of travellers every year: we have been offering PCR as an immediate diagnostic test for travellers’ diarrhoea and gastroenteritis since 2016 and were the first medical practice in the UK to do this..
What bugs can the Gastrointestinal (GI) Panel detect?
The test looks for the top 23 causes of travellers' diarrhoea.

Can you still help if I am still abroad?
Yes - but a little preparation may be needed.
If you think you might need to have a GI Panel PCR test whilst abroad, it is best to travel with a faecal transport swab, which can be purchased from us at low cost.
The GI PCR test uses tiny stool samples taken with a swab and preserved in vial containing transport medium, that can easily be preserved and sent back to the clinic from abroad for analysis. The ideal option would be to send it to us by overnight courier which would provide next day results.
Faecal transport swabs are available at Fleet Street Clinic to purchase during your consultation or via our online shop.
If you find yourself aboard needing a GI PCR test and you don’t have one of our swabs, we may still be able to help. You should phone the laboratory for more information.
Diarrhoea can persist for weeks afterwards, there are a number of possible reasons, and they do warrant medical advice and further investigation. The PCR technique is sensitive enough to detect traces of organisms, perhaps days after recovery – making it still possible to track down the bug that spoiled your holiday.
Can a GI PCR detect more than one cause?
Yes, about 20% of cases may be mixed infections
Not all cases of travellers’ diarrhoea are due to a single cause, and in about 20% of cases we find mixed infections – involving more than one organism at the same time.
This can explain why initial treatment may sometimes fail to work completely – if the different organisms require different forms of treatment.
PCR can help in this situation since tests as they screen for all pathogens at the same time. Our tests are semi-quantitive so can also give a rough indication of which infection predominates.
Our Patients Speak for Us
Charles Lee
Fleet Street were excellent. Saw me at short notice and provided a good diagnosis of my condition. Their prescriptions were on the money because my infected ear began to clear up soon afterwards.
Richard Andrews
A really great private GP service. Warm, friendly and professional doctors who make you feel special and heard. The appointments are never rushed and you are properly examined and treated. Highly recommended.

I have only had good experiences visiting the Fleet Street Clinic for my vaccinations, and particularly appreciate the flexible, friendly, individualised, swift, efficient and effective service. Thank you all, and see you again soon.
Pamela Cramer
I was treated with kindness and professionalism both during phone calls about whether I was suited to the vaccination and during my visit to the clinic. Follow up was also perfect. Thank you.
Ziad Elmagdoub
Had a great experience at Fleet Street Clinic. I went in for my occupational health clearance and everything was smooth from start to finish. The staff were friendly and professional and the whole process was really straightforward. A special thank you to Chiara from the nursing team who handled my tests. She was not only kind and reassuring but also incredibly professional and easy to talk to. She made what could have been a stressful visit feel completely relaxed.
Victoria Boydell
Easy to book appointments. Friendly and helpful receptionists. Becky, the nurse who has given me my Rabies jabs is a delight. I’m happy to have all my vaccines at Fleet Street.
Mark Tebbit
On repeated occasions over the last year, I have received A1 treatment from the Fleet Street Clinic. Short-notice appointments, face to face and on the phone, for emergency conditions and quick prescriptions from excellent doctors have helped me enormously. The Reception Team are also highly professional. I couldn't recommend it more strongly.
AES
The best in London. I have been coming here for over 20 years. Professional, easy and provide a comprehensive offering. Travel vaccinations, shingles vaccine & most recently covid vaccine.
Paul Vella
Excellent service, had a private Covid and Flu vaccination here arrived early and was called in by the nurse almost immediately, very pleasant surroundings and lovely stuff would use again worth £125 to get protected as not eligible for free vaccinations.
Ken McLean
This is a professional set up, first communications by telephone gave me positive vibes. Clinic is in a great central London location. Nurse doing the 'jabbing' was knowledgeable and slick! I will go back for future vaccinations.
FAQs
Travellers’ diarrhoea is caused by drinking water or eating foods that contaminated with viruses, bacteria or parasites. Travellers’ diarrhoea is the most common illness in travellers travelling to hot countries and places where food hygiene is unreliable.
More information on Travellers’ diarrhoea
Yes, we have a free online Travellers’ Diarrhoea Consultation which asks you a few questions about your upcoming travels and determines if you are suitable for a Travellers’ Diarrhoea Kit – you can then choose to purchase this kit.
The kit is also available when you attend our Travel Clinic.
According to NaTHNaC, bacteria are the most common cause of Travellers’ Diarrhoea; most commonly enterotoxigenic Escherichia coli, followed by Campylobacter jejuni, Shigella spp., and Salmonella spp. Giardia infection is the commonest cause of diarrhoea persisting on return home.
As one of the leading independent specialist travel clinics in the UK, we look after large numbers of travellers every year: we were the first clinic to offer PCR as a “point of care” diagnostic test for travellers’ diarrhoea and have been using it for in-clinic diagnosis of travellers’ diarrhoea and related infections since 2016. PCR is not new, but the Fleet Street Clinic is one of the only places in the UK that can deliver results at the same appointment.
