A TB test, also known as a tuberculosis test, is used to determine if a person has been exposed to the bacteria that causes tuberculosis. There are two types of TB tests: the Mantoux tuberculin skin test and the TB blood test. To determine if a TB test is positive, healthcare providers look for a reaction at the injection site of the Mantoux test or for the presence of certain proteins in the blood for the TB blood test.
In the Mantoux test, a small amount of tuberculin protein is injected under the skin of the forearm. After 48 to 72 hours, a healthcare provider will check for a reaction, which presents as a raised, red bump at the injection site. If the bump measures a certain size (usually 5 mm or larger), the test is considered positive and further testing may be needed.
For the TB blood test, blood is drawn and tested for the presence of antibodies that are produced in response to the TB bacteria. If these antibodies are found in the blood, the test is considered positive.
It is important to note that a positive TB test does not necessarily mean that a person has active tuberculosis. Further testing, such as chest X-rays and sputum tests, may be needed to determine if treatment is necessary. If a TB test is positive, it is crucial to follow up with a healthcare provider for proper evaluation and treatment.
