Check for itching around the anus, especially at night
Use clear tape to press against the skin around the anus first thing in the morning before bathing or using the toilet
Place the tape on a clean glass slide or seal it in a bag for testing
Repeat the tape test on 3 separate mornings if needed
Have a healthcare provider examine the sample under a microscope
Look for tiny white worms in the stool or around the anal area
Contact a healthcare provider for confirmation if symptoms persist
