Mantoux Skin Test (PPD) Information
Please read this information before you get the PPD skin test!
What is tuberculosis (TB)?
TB remains an important cause of disease in the United States and throughout the world. The incidence of TB has recently increased, and therefore, early medical detection is recommended when there is a possibility of infection. This is done through the PPD test. The bacteria that cause TB are treatable with antibiotics; the earlier the diagnosis the easier the treatment.
What is the Mantoux Skin Test: this is a test for exposure to the bacteria that causes the disease - it is not a vaccine against a disease.
The material used to test for tuberculosis is called “PPD” or “Purified Protein Derivative”. The test is performed by injecting a small amount of PPD into the skin of the forearm to form a small bubble. This area of the forearm is examined 2-3 days after injection to see if it is red or swollen. Positive skin test does not necessarily mean that a person has active tuberculosis but usually indicates that a person has been exposed to tuberculosis at some time in the past. Individuals with positive skin tests will be referred to a physician or nurse practitioner.
What are the side effects from this test?
Serious side effects from skin testing are very rare. Individuals who are sensitive to PPD may experience fever, swollen glands in their arms or underarms, skin rashes, and/or ulcers at the site of skin testing. Very rarely does this happen. Cold packs may be applied for symptomatic relief of pain, itching and discomfort. Positive reactions may result in scarring at the test site. As with any medication, there is always the possibility of an allergic reaction but this is very unusual.
When should you get a PPD test?
Health Services advises all incoming students to have a PPD, and all students entering UNH from areas of high risk to have a PPD within four weeks (of their arrival). Certain physical exams, internships, or travel plans require a PPD. Health care workers are required to have a PPD each year 3-6 months after return from travel to a high-risk area
Who should not have a PPD test?
- Those who have had a documented positive Mantoux skin test in the past
- Those who have received live virus immunizations such as Measles, Mumps, and Rubella (MMR) vaccines in the past 6 weeks
- Those who have had a viral infection such as MMR or chicken pox in the past 6 weeks
- Those who have taken corticosteroids or immunosuppressive medications, (i.e., immunoglobulin) in the past 6 months
Please note: In order to receive the results of this test you must return to Health Services in 2 to 3 days so that the results of the test can be verified. Otherwise, the test must be repeated.
