Know more about this test

The Mantoux Test, also known as the Tuberculin (TB) Skin Test (TST), is a widely used method to determine if a person has been exposed to tuberculosis (TB) bacteria. During the test, a small amount of purified protein derivative (PPD) tuberculin is injected just beneath the skin of the forearm. After 48 to 72 hours, a healthcare professional examines the injection site for a raised, hard swelling (induration). The size and characteristics of this reaction help indicate whether the body has mounted an immune response to TB bacteria, suggesting previous exposure or infection. The Mantoux Test is safe, minimally invasive, and suitable for people of all ages. It is often used for screening individuals at risk of TB, including those in close contact with TB patients, healthcare workers, or people with weakened immune systems. While it does not confirm active TB disease, it helps guide further diagnostic testing, preventive therapy, and timely medical intervention if needed. It is available at an affordable price in Greater Noida with our partnered labs.

Understanding Mantoux Test

Tuberculosis is an infectious disease caused mainly by Mycobacterium tuberculosis, primarily affecting the lungs but potentially other organs as well. The disease can remain latent (inactive) without symptoms or progress to active infection, causing symptoms like persistent cough, fever, night sweats, and weight loss. The Mantoux test helps identify latent TB infection and supports active TB diagnosis when combined with clinical and radiological tests.

No special preparation is required for the mantoux test procedure. Do not scratch, rub, or apply creams to the injection site after the test, as this may affect the results. Keep the area clean and dry. Inform your doctor about all the medications or supplements that you are taking, as these may affect the test results, potentially requiring temporary discontinuation before the test.

Mantoux test result ranges may vary across the laboratories depending on the methodology and laboratory guidelines. Do not self-medicate. Always consult your doctor to understand your test results correctly.

Disclaimer: You must visit your nearest Tata 1mg partnered lab facility for radiology tests.

What are the Symptoms or Conditions That May Require the Mantoux Test?

You may need the Mantoux Test if:

  • You were in close contact with someone with active TB
  • You work in healthcare or high TB-risk environments
  • You have symptoms like a cough >3 weeks, fever, night sweats, or weight loss
  • You have conditions that weaken immunity
  • You need screening before immunosuppressive therapy or organ transplant
  • You live in or come from high TB-prevalence areas
  • You had the Bacillus Calmette-Guérin (BCG) vaccine and need TB exposure screening

It does not confirm active TB but shows immune sensitization to TB bacteria.

When Would I Need the Mantoux Test?

You may need the Mantoux Test if you:

  • Have been in close contact with someone who has active TB
  • Work in healthcare or other high TB-risk environments
  • Show symptoms of TB, such as a cough lasting more than 3 weeks, fever, night sweats, or unexplained weight loss
  • Have conditions that weaken your immune system, making you more susceptible to TB
  • Need screening before immunosuppressive therapy or organ transplantation
  • Live in or come from areas with high TB prevalence
  • Have had the BCG vaccine and need screening for TB exposure

How Do I Prepare for the Mantoux Test?

Do I need to fast or stop any medications before the Mantoux Test test?

No special preparation, like fasting, is required. However, inform your healthcare provider if you:

  • Have recently received a live vaccine (like measles or chickenpox)
  • Are pregnant
  • Have a history of allergic reactions
  • Have skin conditions or scars on your forearm
  • Have received a Bacillus Calmette-Guérin (BCG) vaccine
  • Avoid applying creams, lotions, or antibiotics to the forearm before the test.

How is the Mantoux Test Done?

  • The inner forearm is cleaned with alcohol.
  • 0.1 ml of PPD tuberculin is injected under the skin to form a small bump.
  • Do not scratch or cover the site.
  • Return after 48–72 hours to have the test read.

What Happens During the Test?

  • Following the injection, a small, painless lump will appear.
  • No immediate reaction or swelling is usually noticeable.
  • After 2–3 days, the site is examined for firmness and measured by the healthcare provider.

What Happens After the Mantoux Test?

  • The healthcare provider measures the diameter of induration (firm swelling) at the test site.
  • The reading is recorded in millimeters using a ruler or caliper.
  • The result is interpreted based on size thresholds tailored to your risk profile.
  • No special care is needed after the reading.

Is the Mantoux Test Painful?

The test is generally painless except for the needle prick. Mild itching or redness may appear but usually resolves quickly.

How Long Does the Mantoux Test Take?

The injection takes a few seconds. The test must be read 48–72 hours later, requiring two visits.

When Will I Get the Results?

Mantoux Test result time may vary depending on your location and the laboratory where the test is conducted. In general, Tata 1mg provides the results within the stipulated time after sample collection.

What does Mantoux Test measure?

The Mantoux Test measures delayed-type hypersensitivity, an immune reaction to TB proteins. The purified protein derivative (PPD) tuberculin injection triggers a localized response if the individual has been exposed to TB or related bacteria. The firm swelling (induration) is measured in millimeters and reflects immune sensitivity. Redness alone is not considered. The size of the induration, along with risk factors and history, determines a positive or negative result.

What Do the Results Mean?

Interpretation depends on the size of induration and individual risk factors:

  • Induration of 5 mm or more is considered positive in:
  • HIV-infected individuals
  • Recent contacts of TB patients
  • Individuals with chest X-ray abnormalities consistent with old TB
  • Immunosuppressed patients (organ transplant recipients, those on immunosuppressive therapy)
  • Induration of 10 mm or more is positive in:
  • Recent immigrants from high-prevalence countries
  • Injection drug users
  • Residents and employees of high-risk congregate settings
  • Mycobacteriology lab personnel
  • People with clinical conditions that increase TB risk (diabetes, chronic renal failure)
  • Induration of 15 mm or more is positive in individuals with no known risk factors for TB.

A positive Mantoux Test indicates TB infection but does not differentiate latent from active disease. Additional investigations may be required.

What Do Normal Mantoux Test Results Mean?

A normal or negative Mantoux Test usually means you have not been exposed to TB bacteria. The swelling at the injection site is small, typically less than 5 mm for high-risk people and less than 15 mm for those with no known risk.

However, a negative result does not completely rule out TB, especially if:

  • Exposure was very recent (less than 8 weeks)
  • Your immune system is weak (e.g., HIV, malnutrition, certain illnesses)
  • You are very young or severely ill

In such cases, repeat testing or further checks may be needed. Overall, a normal test generally suggests no TB infection, but your doctor will consider your symptoms, history, and risk factors for a proper diagnosis.

What Do High Levels of Mantoux Test Induration Indicate?

A larger swelling (5 mm or more, depending on your risk) shows your immune system has reacted to TB bacteria. This means you have likely been exposed.

A positive test does not tell if TB is active or inactive. Further tests, like chest X-rays or sputum exams, are needed to find out if the infection is currently active.

What Should I Do If My Mantoux Test Is Positive?

Do not panic. Many people with latent TB (inactive infection) remain healthy with monitoring or preventive treatment.

Consult your doctor for further evaluation. They may suggest additional tests to check if you have active TB and plan treatment if needed. Early diagnosis and care reduce the risk of disease spreading or worsening.

What Do Low or Negative Mantoux Test Results Indicate?

A low or negative result shows little or no immune response, suggesting no prior TB exposure or an inadequate immune reaction.

False negatives can happen if:

  • TB exposure was recent (within 8 weeks)
  • Your immune system is weak (HIV, chemotherapy, malnutrition)
  • You are very young

If you have TB symptoms or are high-risk despite a negative test, repeat testing or other investigations may be needed.

Can Mantoux Test Results Be Inaccurate?

Yes, sometimes the results may not be accurate. Factors that affect results include:

  • Weak immune system (HIV/AIDS, malnutrition, very young age)
  • Prior BCG vaccination or non-TB bacterial infections (may cause false positives)
  • Improper test procedure or reading

If your test result does not match your symptoms or risk, your doctor may recommend repeating the test or using other diagnostics like interferon-gamma release assays (IGRAs) or chest X-rays to confirm TB infection.
