The results of this test must be interpreted carefully. The person's medical risk factors determine at which increment (5 mm, 10 mm, or 15 mm) of induration the result is considered positive. [12] A positive result indicates TB exposure. 5 mm or more is positive in An HIV-positive person; Persons with recent contacts with a TB patient
The equivalent Mantoux test positive levels done with 10 TU (0.1 mL 100 TU/mL, 1:1000) are 0–4 mm induration (Heaf 0-1) 5–14 mm induration (Heaf 2) >15 mm induration (Heaf 3-4) The Mantoux test is preferred in the United States for the diagnosis of tuberculosis; multiple puncture tests, such as the Heaf test and Tine test, are not recommended.
Injecting a Mantoux skin test The Mantoux test for TB involves intradermally injecting PPD (Purified Protein Derivative) tuberculin and measuring the size of induration 48-72 hours later. The Mantoux skin test is used in the United States and is endorsed by the American Thoracic Society and Centers for Disease Control and Prevention .
The tine test is a multiple-puncture tuberculin skin test used to aid in the medical diagnosis of tuberculosis (TB). The tine test is similar to the Heaf test, although the Mantoux test is usually used instead. There are various forms of the tine tests which usually fall into two categories: the old tine test (OT) and the purified protein ...
With experience gained from the tuberculin skin test during the greater part of the last century, the current body of medical knowledge and advances were made possible by Robert Koch. Through the failures and successes of tuberculin, more than ever before is known about the causes and symptoms of tuberculosis and the measures to prevent it.
[119] [120] [121] Part of the reasoning against the use of the vaccine is that it makes the tuberculin skin test falsely positive, reducing the test's usefulness as a screening tool. [121] Several vaccines are being developed. [14] Intradermal MVA85A vaccine in addition to BCG injection is not effective in preventing tuberculosis. [122]

The test is used to evaluate people for latent tuberculosis (TB) infection. Reason High technical standard and resolution, showing a common test that nearly everyone has to take. Bring attention to TB. A third of the world's population are thought to be infected with M. tuberculosis, and new infections occur at a rate of about one per second.
