Tuberculosis (TB) remains one of the most significant infectious diseases worldwide, making early detection and treatment essential for maintaining good health. If you have been exposed to someone with TB or are experiencing symptoms such as a persistent cough, fever, or unexplained weight loss, getting a TB test is a crucial step in protecting yourself and those around you. Understanding what is a TB test, how it works, and when you should get tested can help you take the right preventive measures.
What Is a TB Test?
A TB test is a medical procedure used to determine whether a person has been infected with the bacteria Mycobacterium tuberculosis. There are two primary types of TB tests: the TB skin test (also known as the Mantoux test) and blood tests (Interferon-Gamma Release Assays or IGRAs). Both methods are designed to detect TB infection but work in slightly different ways.
The TB skin test is the most common and cost-effective screening tool. During this test, a small amount of purified protein derivative (PPD) is injected just under the skin of your forearm. After 48 to 72 hours, a healthcare professional checks the injection site for swelling or a raised bump. A positive result indicates that the person has been exposed to the TB bacteria, though it does not necessarily mean they have active TB disease.
How the TB Skin Test Works
The TB skin test is simple, quick, and painless. After the PPD is injected, your body’s immune system will react if you have been infected with the TB bacteria. The reaction usually appears as a small bump or hard area at the site of injection. The size of this reaction is measured in millimeters to determine whether the result is positive or negative. A positive test often requires further evaluation, such as a chest X-ray or blood test, to determine if active TB disease is present.
Why a TB Test Is Important
Tuberculosis can remain dormant in the body for years without causing symptoms, known as latent TB infection. Without treatment, latent TB can develop into active TB, which is contagious and potentially life-threatening. Getting a TB test is especially important for people who:
Have been in close contact with someone diagnosed with TB.
Work in healthcare settings or environments where TB exposure is more likely.
Have weakened immune systems.
Travel frequently to regions with high TB infection rates.
Early detection allows for prompt treatment, reducing the risk of spreading TB and protecting overall community health.
