Test information
Intestinal parasitic infections are widespread throughout the world and are a frequent cause of disorders of the digestive tract, allergic diseases, and general somatic disorders. There are several hundred types of parasites that can cause disease in humans. Most often, intestinal parasitic infections are caused by such helminths as roundworms, hookworms, pinworms, bovine and porcine tapeworms, trichinella, and also the protozoa - giardia, amoeba. Infection is possible with non-observance of sanitary and hygienic standards, poor purification of drinking water, consumption of unwashed vegetables and fruits, insufficient heat treatment of meat and fish.
Clinical manifestations of intestinal parasitosis vary from asymptomatic carriage to severe diarrhea, intense abdominal pain, signs of impaired nutrition and absorption of nutrients, and severe anemia. The main diagnostic method that allows you to detect helminth eggs and cysts of protozoa and confirm the clinical diagnosis is light microscopy of feces. However, in connection with the non-constant release of helminth eggs and protozoan cysts, with a negative result of any microscopic analysis of feces and persistent clinical symptoms, repeated examinations of feces may be required at intervals of several days.
