Generally, ultrasonography and pathogenetic examination can be carried out to check whether there are parasites in the human body. It is recommended to carry out the examination in regular hospitals and carry out reasonable treatment under the guidance of specialized doctors. 1. Ultrasonography: If multiple stripes appear under ultrasonography, which can be changed when moving, it basically proves the existence of parasites in the body. 2. Pathogenetic testing: Pathogenetic testing can be done in regular hospitals to detect the presence of parasites in the body through feces or terminal blood smears. For example, feces can detect roundworms, hookworms, etc., and terminal blood can detect worms, plasmodium, etc.. The presence of parasites in a person’s body may be accompanied by abdominal pain, bloating, and other uncomfortable symptoms. If the parasite resides in the head, there may be fever, headache and other symptoms. It is recommended to go to the hospital for examination and treatment.
