The TB skin test is one method. It may also be known as a Mantoux tuberculin skin test. It is inexpensive and the test method most are familiar with who have had TB test before. A TB skin test is an injection of a purified protein derivative injected under the skin. Most people who ...
The IGRA test has largely replaced the Mantoux skin test, which is performed by injecting a purified protein derivative of mycobacterium tuberculosis under the skin on your forearm. If you have an immune reaction, swelling will result at the injection site within two to three days.3 Sometimes...
a small amount of fluid known as tuberculin is injected beneath the skin. In 48-72 hours, the patient returns to the health care provider to have the health care provider look for a reaction at the site of the injection. The skin test is also known as a tuberculin skin test...
