Dientamoeba fragilis
Dientamoeba fragilis is a single-celled parasite that resides in the human gastrointestinal tract. It is linked to dientamoebiasis, a condition that may cause various digestive symptoms. Its exact mode of transmission and role in disease remain under investigation.
Description
Dientamoeba fragilis is a protozoan parasite that, despite its name, is more closely related to flagellates than amoebas. It is often detected in individuals with gastrointestinal complaints, but its role as a causative agent of disease is still debated. It lacks a cyst stage, which is unusual for intestinal parasites, making its mode of transmission somewhat unclear.
- Diarrhea or loose stools
- Abdominal pain or discomfort
- Bloating and gas
- Nausea
- Fatigue
- Weight loss (in chronic cases)
- Anal itching
The exact transmission route of Dientamoeba fragilis is not well understood. It has been hypothesized that it might be transmitted via the fecal-oral route, potentially through contaminated food or water. Another theory suggests that it could be transmitted through parasitic worm eggs, such as those of pinworms. Because Dientamoeba fragilis lacks a protective cyst stage, it’s thought to be less resilient in the environment compared to other parasites.
- Practice good hand hygiene, especially after using the bathroom and before eating.
- Ensure safe and sanitary food and water consumption, particularly in areas where the parasite might be prevalent.
- Regularly clean and disinfect bathroom facilities and kitchen areas.
- Consider regular deworming in areas where intestinal worms are common, as a precaution if the worm egg theory of transmission is valid.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
