Mantoux test is a diagnostic method for detecting tuberculosis (TB) infection. It is also known as the tuberculin skin test (TST).It aids in determining whether a person has come into contact with the TB-causing bacterium. A tiny amount of pure protein derivative (PPD), or tuberculin, is injected under the skin during the test. An elevated, hard region at the injection site will result from the immune system of an individual carrying a TB infection reacting to the PPD. This response could be a sign of tuberculosis infection and call for more testing.
A medical expert cleans the forearm before starting the Mantoux test procedure. Then, a small amount of tuberculin is injected beneath the skin's outermost layer using a tiny needle. There will be a little bump where the injection was made. To have the injection site examined, the patient needs to go back to the doctor within 48 to 72 hours. To determine the outcome, the healthcare expert measures the size of any swelling. Although additional testing is required to prove current TB disease, a bigger reaction typically implies TB exposure.
The Mantoux test, also known as the tuberculin skin test, detects tuberculin infection by injecting tuberculin into the skin. The immune system responds to exposure to tuberculosis bacteria, resulting in an elevated area at the injection site.
The Mantoux test procedure involves Injecting 0.1 ml of tuberculin PPD under the forearm skin. There ought to be a tiny lump. After 48 to 72 hours, the location needs to be examined for response.
When the Mantoux test is positive, there is a significant swelling at the injection site, suggesting possible tuberculosis contact. However, more testing is required to confirm the presence of active tuberculosis.
A normal Mantoux test shows a small, non-significant reaction (less than 5mm of swelling) that suggests no tuberculosis infection. The precise cut-off, however, varies according on risk factors and medical history.
To read a Mantoux test result, measure the induration (raised, hardened region) at the injection site after 48-72 hours. The test results are either positive or negative based on the size of the induration.
No, the accuracy of the Mantoux test is not perfect. It can produce false-negative results in those who have recently been infected or immunocompromised, and false-positive results in those who have received the BCG vaccination. Always consider your health care professional opinion and suggestions.
