Are you suffering from gastrointenstinal problems following a trip abroad? Thanks to our state-of-the-art PCR equipment, Fleet Street Clinic can give you an accurate diagnosis of the cause and provide the correct treatment, right away.
PCR stands for “polymerase chain reaction” – a biochemical method of searching samples for the tiniest traces of genetic material belonging to disease-causing organisms, and then amplifying them to a point where they can be easily detected. PCR tests are highly sensitive, so all we need is a tiny sample.
A stool sample is taken using a tiny swab. The swab goes into a small plastic tube containing 2ml of preservative, and can be tested right away. The sample takes 65 minutes to process.
The test looks for the top 22 causes of traveller’s diarrhoea. All of these are tested for all 22 organisms at exactly the same time – and in about 20% of travellers with diarrhoea, more than one bug turns out to be responsible. Here is a complete list of the bacteria, viruses and parasites we test for:
Bacteria: Campylobacter (jejuni, coli & upsaliensis),Clostridium difficile (Toxin A/B), Plesiomonas shigelloides, Salmonella, Yersinia enterocolitica, Vibrio (parahaemolyticus, vulnificus, & cholerae), Vibrio cholerae
Diarrheagenic : E. coli/Shigella E. coli O157, Enteroaggregative E. coli (EAEC), Enteropathogenic E. coli (EPEC), Enterotoxigenic E. coli (ETEC) lt/st, Shiga-like toxin-producing E. coli (STEC) stx1/stx2 E. coli O157, Shigella/Enteroinvasive E. coli (EIEC)
Viruses: Adenovirus F 40/41, Astrovirus, Norovirus GI/GII, Rotavirus A, Sapovirus (I,II, IV, and V)
Parasites: Cryptosporidium, Cyclospora cayetanensis, Entamoeba histolytica, Giardia lamblia
