After having a tuberculosis (TB) test, it is normal to experience redness at the injection site. This redness is a common side effect of the test and should not typically cause concern. The TB test, also known as the Mantoux test or tuberculin skin test, involves injecting a small amount of purified protein derivative (PPD) into the skin on the forearm. The test is then read 48 to 72 hours later to determine if there is a reaction indicating a possible TB infection.
The redness at the injection site is known as a local reaction and is a result of the body’s immune response to the PPD injection. This reaction typically presents as a raised, red bump at the injection site, known as an induration. It is important to note that the presence of redness or induration does not necessarily indicate a positive TB infection, as other factors can contribute to a reaction on the skin.
In most cases, the redness and induration will resolve on their own within a few days. However, if the redness becomes increasingly painful, swollen, or exhibits signs of infection such as pus or drainage, it is important to seek medical attention. Overall, redness after a TB test is a normal part of the testing process and should not typically cause alarm.
