What is the difference between PPD and Mantoux?
Mantoux refers to the technique for administering the test. Tuberculin (also called purified protein derivative or PPD) is the solution used to administer the test. The preferred term for the test is tuberculin skin test, or TST.
What is Mantoux 5tu PPD test?
The Mantoux test or Pirquet test or PPD test for purified protein derivative is a skin test that is used to diagnosis if someone has tuberculosis. The basis of the reading of this test is to identify the presence or absence of the amount of induration (localised swelling).
Is 10 mm PPD positive?
An induration of at least 10 mm may be considered a positive test if you’re a recent immigrant from a country with a high prevalence of TB. The same is true if you live in a high-risk environment such as a nursing home or work in a high-risk setting such as a hospital or medical laboratory.
How many MM is a positive Mantoux test?
An induration of 15 mm or more is considered positive in: Always considered positive in any person. Healthy individuals without any risk factors for TB.
Can any RN read a TB test?
The tuberculin skin test must be given and read by a professional who has been trained to do this, and has been informed of the most recent guidelines in tuberculosis control. Never allow anyone other than a nurse or physician to read a tuberculin skin test.
What does 5tu mean?
The standard recommended tuberculin test, known as the Mantoux test, is administered by injecting a 0.1 mL of a liquid containing 5 TU (tuberculin units) of PPD into the top layers of skin (intradermally, immediately under the surface of the skin) of the forearm.
How does a PPD test work?
The test is done by putting a small amount of TB protein (antigens) under the top layer of skin on your inner forearm. If you have ever been exposed to the TB bacteria (Mycobacterium tuberculosis), your skin will react to the antigens by developing a firm red bump at the site within 2 days.
How do you read TB results?
The skin test reaction should be read between 48 and 72 hours after administration by a health care worker trained to read TST results. A patient who does not return within 72 hours will need to be rescheduled for another skin test. The reaction should be measured in millimeters of the induration (firm swelling).
Can I read my own PPD?
You can read your own PPD for the sake of information, but you should have someone else read it and do the documentation to eliminate any appearance of a conflict of interest. No patient should read his or her PPD even though some can tell if it is positive but it’s not that they are reading it.

What is the tuberculin skin test?
