Tuberculosis (TB) is a serious infectious disease caused by Mycobacterium tuberculosis, primarily affecting the lungs but sometimes targeting other parts of the body. Early detection is critical, and one of the most common methods for screening is the TB skin test. If you’re wondering what a TB test is and how it works, this guide will walk you through the process, what to expect, and where to get tested, including at trusted locations like Specialty Care Clinics Corsicana.
What is a TB Test?
A TB test is a diagnostic tool used to determine if a person has been exposed to the tuberculosis bacteria. There are two main types: the TB skin test (Mantoux test) and TB blood tests (interferon-gamma release assays). The focus here is on the TB skin test, which remains widely used for its reliability and ease of administration.
How the TB Skin Test Works
During a TB skin test, a small amount of purified protein derivative (PPD) is injected just beneath the skin of your forearm. This procedure is simple and minimally invasive. After 48 to 72 hours, a healthcare professional examines the injection site for a raised, hard area or swelling, which indicates your immune system's response to the TB bacteria.
It’s important to understand that a positive result does not always mean active TB—it indicates exposure. Further tests, such as chest X-rays or sputum analysis, may be required to confirm whether the infection is active or latent.
What to Expect During the Test
Before the test, a healthcare provider may ask about your medical history, previous TB exposure, and any medications you are taking. After the injection:
You may experience slight redness or itching at the site.
Avoid scratching or applying creams to the area.
Return within 48–72 hours for the test reading.
A trained professional at Specialty Care Clinics Corsicana ensures accurate administration and interpretation of your TB skin test, making it a safe and reliable option.
