What is the importance of flatworms?
Through their large surface compared to their volume they can exchange gases like carbon dioxide, oxygen and ammonia across bodies. Flatworms can adapt to many conditions, which makes them able to adapt to an enormous variety of habitats. They play important roles for healthy streams, ponds, and lakes.
How do flatworms affect humans?
They feed on blood cells and cause a disease called schistosomiasis. The symptoms vary, depending on which parts of the body the worms inhabit, but can include fever, abdominal pain, coughing, diarrhea, and enlargement of the liver and spleen.

Is there a home test for parasites?
About the Parasitology Test: By using a simple at-home stool test, the Parasitology test is a direct examination of stool for ova and parasites (O&P) in order to determine the presence of parasites and/or their eggs in the gastrointestinal tract. O&P is considered the gold standard of diagnosis for many parasites.
