Success! In Clinical Laboratory Science – Parasitology Practice Test

Eggs are laid around the anus by the female worms, so the most effective diagnostic material is a perianal specimen. Using a piece of clear adhesive tape or a perianal swab pressed to the skin first thing in the morning captures the eggs, which are then seen under the microscope. Eggs in feces are not routinely found or reliable for diagnosis, and adults or larvae in stool do not reflect the typical shedding pattern. This perianal collection method is the standard way to diagnose Enterobius vermicularis infection.
