Overview
The "Mantoux test Tuberculin test (10TU)" is a clinically important tool used for tuberculosis (TB) screening and diagnosis. It involves injecting purified protein derivative (PPD) tuberculin intradermally and evaluating the induration at the injection site after 48 to 72 hours. This test is primarily utilized to screen individuals at risk of TB exposure and to aid in the diagnosis of latent TB infection or active TB disease. A positive Mantoux test indicates a delayed hypersensitivity response to PPD tuberculin, suggesting the presence of a latent TB infection or active TB. It serves as a valuable aid in identifying individuals who require further evaluation and management, such as preventive therapy for latent TB or timely initiation of treatment for active TB cases.
Reasons for Undergoing the Mantoux Test
The Mantoux test, also known as the tuberculin skin test (TST), is a valuable tool for detecting tuberculosis (TB) infection. There are several important reasons to undergo this test.
- Primarily, the Mantoux test is used for screening individuals to determine if they have been exposed to Mycobacterium tuberculosis, the bacteria responsible for TB. This is crucial for early detection and prevention of TB spread.
- The Mantoux test is also used to conduct a baseline TB risk assessment for individuals at higher risk of infection. This includes people who have had close contact with TB patients, healthcare workers, and residents of high-risk environments such as correctional facilities and shelters.
- Additionally, the test helps evaluate symptoms that may suggest TB, aiding in differentiating between latent TB infection, where the bacteria remain dormant, and active TB disease, where the bacteria cause illness and are potentially contagious.
- Monitoring high-risk populations is another important reason for the Mantoux test. Individuals with severe immunocompromise, such as those with HIV infection or other chronic medical conditions, are more vulnerable to TB.
- Early identification through the Mantoux test helps in providing timely treatment, reducing the risk of progression to active disease and improving overall health outcomes.
List of Parameters Considered During the Mantoux Test
During the Mantoux test, the primary parameter measured is the extent of induration (firm swelling) at the injection site.
- Induration Size: The diameter of the induration is measured in millimetres, indicating the body's immune response to the injected tuberculin-purified protein derivative (PPD).
- 5 mm or more is considered positive in high-risk groups such as HIV-positive individuals, recent contacts with a TB patient, and immunosuppressed patients.
- 10 mm or more is considered positive in groups such as recent arrivals from high-prevalence countries, injection drug users, and residents of high-risk congregate settings.
- 15 mm or more is generally considered positive in most individuals, indicating a strong immune response to the PPD.

Frequently Asked Questions
This test evaluates your body's immune response to tuberculin.
• To screen for tuberculosis and to aid in the diagnosis of TB infection • To evaluate the effectiveness of TB treatment • To assess your risk of developing active TB disease
Your doctor might recommend this test if you • have been in close contact with someone who has infectious TB, • show signs or symptoms of active TB, such as persistent cough, weight loss, night sweats, and fever, • have a weakened immune system and are at a higher risk of developing TB, or • have a positive result from other TB screening tests.
An abnormal result does not mean you have active TB but indicates exposure to TB bacteria or a latent TB infection. Further tests may be needed for confirmation.
During the test, a small amount of tuberculin is injected under the top layers of your skin, usually on your forearm. You will need to visit the laboratory again 48 to 72 hours later for the test results.
• Inform your doctor about any medications you are taking. • Avoid applying creams or lotions to the area where the test will be done. • Follow any other instructions provided by your doctor. Also, tell them if you have any specific requirements.
• Sputum Culture: This test is done to identify the specific bacteria causing the TB infection and determine their sensitivity to various antibiotics. • Interferon-Gamma Release Assays (IGRAs): These blood tests help detect TB infection by measuring your immune response to TB antigens.
Mantoux skin test or tuberculin skin test
Tuberculosis (TB) is an infectious disease caused by bacteria called Mycobacterium tuberculosis. It primarily affects the lungs but can also affect other parts of the body. TB spreads through the air when an infected person coughs or sneezes, and it can be a serious condition if left untreated.
The Mantoux test is a tuberculin skin test that determines if a person has been infected with tuberculosis-causing bacteria. It involves injecting purified protein derivative (PPD) into the forearm's dermis and measuring the reaction after 48-72 hours.
A normal Mantoux test result is indicated by minimal or no swelling (induration) at the injection site. Typically, an induration of less than 5 mm is considered negative for tuberculosis. However, interpretation of the result may vary based on individual risk factors, such as a person's exposure to TB or underlying medical conditions, which may affect the threshold for positivity.
The Mantoux test detects the body's immune response to tuberculin, which indicates whether a person has been exposed to Mycobacterium tuberculosis, the bacteria that cause tuberculosis (TB). A positive reaction suggests a past or current TB infection. However, the Mantoux blood test cannot differentiate between latent TB, where the bacteria are inactive, and active TB, where the infection is causing symptoms.
Mantoux test reports indicate the size of the induration (swelling) at the injection site. A positive result, typically an induration of 5 mm or more, suggests exposure to TB bacteria. A negative result, with minimal or no induration, indicates no exposure or a possible weakened immune response, which could affect the test's accuracy in some cases.
A positive Mantoux test indicates exposure to TB bacteria. Further tests, such as chest X-rays and sputum samples, are needed to determine if the infection is latent or active. Treatment for latent TB may be recommended to prevent active TB development.
The benefits of the Mantoux test include early detection of TB infection, identification of latent TB, screening of high-risk populations, and its low cost and simplicity compared to other diagnostic methods.
No, fasting is not required before taking the Mantoux blood test. The test involves a simple injection of PPD into the skin and does not require any preparatory dietary restrictions.
The Mantoux test requires two visits to a healthcare provider: the first visit is for the injection, and the second visit is 48–72 hours later to assess the reaction. The entire process usually takes about 3 days.
