Tuberculin Skin Test in Children: Care Instructions

What is it?

Tuberculosis (TB) is a bacterial infection that can damage the lungs or other parts of the body. The TB skin test can tell if your child has TB bacteria in his or her body. Many people are exposed to TB and test positive for TB bacteria in their bodies, but they don't get the disease. TB bacteria can stay in your child's body without making him or her sick. This is because your child's immune system can keep TB in check.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

  • Do not let your child scratch the test site. Scratching it may cause redness or swelling. This could affect the test results.
  • To ease itching, put a cold face cloth on the site. Then pat the site dry.
  • Do not cover the test site with a bandage or other dressing.

When should you call for help?

Watch closely for changes in your child's health, and be sure to contact your doctor or nurse call line if:

  • You did not have your child's TB skin test checked by your doctor.
  • Your child has a fever or has swelling in his or her arm.
