How are pinworms detected?
Because pinworms usually crawl out of the anus while a child sleeps, the tape test is an easy way to find pinworms. It's best to do this right when your child wakes up and before he or she uses the bathroom or bathes. To do the tape test, pat a piece of clear tape on the skin around the anus. You can then take the tape to your doctor, who can use a microscope to check for pinworms or eggs. It is also possible for you to see the adult worms around the anus during the tape test.
