Your doctor may have you do a tape test. A piece of cellophane tape is pressed against the skin around the anus, and removed. This should be done in the morning before bathing or using the toilet, because bathing and wiping may remove eggs. The doctor will stick the tape to a slide and look for eggs using a microscope.
