Wong's Essentials of Pediatric Nursing Practice Test

The test relies on eggs deposited around the anus at night. To maximize detection, collect the adhesive tape from the perianal skin before any defecation, usually first thing in the morning before bathing or stool passage. Collecting after defecation can miss or dilute eggs, since they may be carried into the stool or wiped away. For best sensitivity, you may repeat the collection on consecutive mornings.
