Is there a way that i can tell if my child has pinworms?

Pinworm diagnosis: Early in the morning, before bathing, look closely at your child's recturm. Pinworms look like tiny white threads, or toilet paper residue. You can do a pinworm tape test and submit to the lab for definitive diagnosis.

Itching: If your child is frequently scratching in the anal area and complains of itching, many doctors will treat for pinworms based on that history. There are some tests that can be done, but may not be easy to do in young children, so some doctors will treat in case of pinworms.
