What's tested in your Gut Bacteria, Worm and Parasite Test?

Bacteria
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).
WHAT'S MEASURED?
- Salmonella is common bacterial infection from contaminated food.
- Shigella is spread by contaminated food or water and sometimes sexual contact.
- Campylobacter is one of the commonest bacterial gut infections.
- E. coli is a common bacteria that all of us have in our gut but some strains can produce a toxin causing gastroenteritis.
Worms
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.
WHAT'S MEASURED?
- Analysis of stool under a microscope to look for worms, parasites and their eggs.
Parasites
Two of the commonest parasites that cause chronic gut symptoms are Cryptosporidia and Giardia. We use PCR testing to pick these up.
WHAT'S MEASURED?
- Giardia is often spread by contaminated water - lakes, rivers or pools. It can cause chronic gut issues with bloating, cramps and diarrhoea.
- Cryptosporidium is one of the commonest parasite infections in the UK. It's often spread via contaminated 'recreational water' such as swimming pools.
