How To Test Tuberculin For Tuberculosis Test?
I want to ask how can the tuberculin drug that is injected into the arm can detect someone who has TB disease. even though as far as we know the disease is in the lungs’. does it have anything to do with it? please enlighten
Hello, Nawansaputra12, thanks for asking HealthReplies.com.
The tuberculin test or Mantoux test is a test that injects a small amount of TB protein (or antigen) into the underside of the skin. This test aims to see if you have been infected with TB before. The skin will be red at the injection site within 2-3 days of being tested if you have been infected with TB before.
In the first TB infection, the immune system will recognize, destroy, and "remember" the M. tuberculosis bacteria. So that on the second exposure, the body's immune system that has remembered it will react by causing an inflammatory reaction. Tuberculosis infection is most often located in the lungs, but our immune system works to cover all organs in the body, so the tuberculin test can detect it. Please note, tuberculin examination cannot detect active TB infection. Other tests are needed to confirm the presence of active TB infection, such as a physical exam, sputum test, and chest x-ray.
For more complete and detailed, you can read the medical literature on the tuberculin test. Hopefully it's useful.
