Questionnaire About Common Symptoms

The presence of protozoa in the intestine manifests in different symptoms. Besides flatulence, abdominal pain and change in stool structure or frequency, the patient can suffer from insomnia, fatigue or skin irritation. In the questionnaire the most common complaints are included. If you have a high score it is useful to order a test for parasites.
These symptoms do not belong exclusively to an infection with parasites and can be caused by a bacterial infection or diseases such as ulcerative colitis, celiac disease, food allergy and other disease. If you have a high score, it is important to consult your doctor.

Thank you for visiting this website. We hope that we have provided you with sufficient information and have answered your questions regarding intestinal parasites. It is our goal to contribute to the diagnosis of intestinal problems, since one in five people suffer from chronic bowel complaints. Stool exams provide a major contribution in identifying the cause of the symptoms. For many people the diagnosis of Irritable Bowel Syndrome, IBS, and testing is of great value since more than 30% of IBS patients are infected with parasites.

Many doctors do not order parasitic tests, the reason is often the unfamiliarity with the subject. Many doctors assume that most people are infected in (sub) tropical regions, and are not aware that infection with parasites is no longer the specialized field of tropical medicine. Through tourism and immigration we all come into contact with intestinal parasites on a daily basis. Children are often contract a infection in kindergarten or school. The laboratory uses advanced DNA testing techniques and offers the test at the lowest possible price.
