What you can do

When you call to make an appointment, ask about performing the tape test. The test involves pressing the adhesive side of a piece of transparent tape to the skin around the anus of the person you suspect has pinworms as soon as the person awakens. The eggs stick to the tape.

You then take the tape to your appointment so the doctor can look for pinworms or eggs under a microscope.

Preparing a list of questions can help you make the most of your time with your doctor. For pinworm infection, some basic questions to ask include:

• If I don't have pinworm infection, what are other possible causes of my symptoms?
• If one family member has pinworms, does the whole family need to be treated?
• How do I rid my home of pinworms?
• How do I prevent reinfection?

What to expect from your doctor

Your doctor is likely to ask a number of questions during your appointment, including:

• When did the itching start?
• Does it occur mostly at night?
• Is there anything that makes the symptoms better or worse?
• Do other family members have similar symptoms?
• Do you know if you or your child has had contact with someone who has pinworms?
• Have you found any dead worms in bedclothes, underwear or in the toilet?

What you can do in the meantime

If you have anal itching, try not to scratch.
