Are you experiencing tuberculosis symptoms and wondering how to get tested for tuberculosis? Here's what you need to know about the Mantoux test, its procedures, and what to expect during the testing process. The Mantoux test price is affordable, and the test is a reliable way to diagnose tuberculosis infection.
What is the Mantoux Test?
The Mantoux test, also known as the tuberculin skin test (TST), is a screening tool for tuberculosis infection. It involves injecting a small amount of tuberculin purified protein derivative (PPD) into the skin of your forearm. If you have been infected with the bacteria that cause tuberculosis, a raised, hard area will develop at the injection site within 48 to 72 hours.
Preparing for the Mantoux Test
Before the test, inform your healthcare provider if you:
· Have recently had a viral illness or live vaccines
· Are pregnant or breastfeeding
· Have a weakened immune system
· Are taking any medications that might affect the test results
The Mantoux Test Procedure
· A healthcare professional will clean an area of your forearm with an antiseptic.
· They will then inject a small amount of PPD just under the skin, creating a small, pale bump.
· You will be asked to return to the healthcare facility 48 to 72 hours later to have the injection site checked.
Interpreting Mantoux Test Results
When you return for the reading, the healthcare professional will measure the size of the raised, hardened area (induration) at the injection site. The test result is considered:
· Positive if the induration is 5 mm or larger in high-risk individuals, 10 mm or larger in medium-risk individuals, or 15 mm or larger in low-risk individuals.
· Negative if the induration is smaller than the above measurements.
A positive Mantoux test indicates that you have been infected with the bacteria that cause tuberculosis. However, it does not necessarily mean you have active tuberculosis disease. Further tests, such as a chest X-ray and sputum culture, may be needed to confirm the diagnosis.
Additional Diagnostic Tests
If your Mantoux test is positive or you have tuberculosis symptoms, your healthcare provider may recommend additional tests, such as:
· Chest X-ray: To look for signs of active tuberculosis in your lungs
· Sputum culture: To check for the presence of tuberculosis bacteria in your sputum (mucus coughed up from the lungs)
· Blood tests: To assess your overall health and rule out other conditions that may cause similar symptoms
Follow-up and Treatment
If you are diagnosed with latent tuberculosis infection (LTBI), your healthcare provider may recommend preventive treatment to reduce your risk of developing active tuberculosis disease in the future. If you are diagnosed with active tuberculosis disease, you will need to undergo a course of antibiotics for several months to treat the infection and prevent its spread to others.
Conclusion
Getting tested for tuberculosis is a straightforward process that typically begins with a Mantoux test. If you suspect that you have been exposed to tuberculosis or are experiencing tuberculosis symptoms, talk to your healthcare provider about getting tested. Early diagnosis and treatment are essential for managing the infection and preventing its spread. The Mantoux test price is reasonable, and the test is widely available at healthcare facilities.
