TB Skin Test: This test is not an immunization, but is a test which we do to determine if your child has been infected with tuberculosis. We do TB skin tests for children with certain risk factors for the disease. Please consult us about doing a TB skin test if your child has been exposed to someone with active tuberculosis, if you are in the health profession with direct patient contact, or if you have traveled outside the United States with your child in the last year. This is especially true for travelers to India. The site of the TB skin test injection should be examined closely at 48 to 72 hours after administration. Any redness or swelling should be reported to the office during regular office hours.
