Which of the following parasites is best detected by the 'Cellophane Tape Test' (Scotch tape test) rather than a routine stool O&P exam?
Show answer and explanation
Correct answer: Enterobius vermicularis
Female Enterobius vermicularis worms migrate to the perianal folds at night to deposit eggs. Because these eggs are rarely found within the fecal mass itself, the tape test is used to pick up eggs directly from the perianal skin.
