A TB skin test, named Mantoux, is used to determine if an individual has been exposed to Tuberculosis (TB) bacteria. It specifically looks for latent TB infection, not active TB disease.

Not everyone infected with TB will display symptoms. There are two conditions: TB disease and latent TB infection (LTBI). LTBI does not show symptoms, is not contagious, while TB disease requires treatment to avoid serious consequences.

TB, which is caused by the bacterium Mycobacterium tuberculosis, can affect any part of the body, with the lungs being the most common site. Symptoms can vary depending on the location. Lung TB symptoms include intense cough, chest pain, sputum (phlegm), and sometimes blood. Other symptoms may include weight loss, loss of appetite, fever, chills, night sweats, weakness, and fatigue.

At Brintnell Pharmacy and Travel Clinic, the TB skin test is performed using tuberculin purified protein derivative. Results are assessed 48-72 hours post-injection. A negative result indicates no infection, while a positive result can suggest latent TB infection or other factors.

False positives can occur due to previous TB vaccination, non-TB mycobacterial infections, errors in reading, cross-reactivity, or recent viral illnesses. If the results are not reviewed within 72 hours, it may require rescheduling.

TB skin tests are crucial for individuals with potential exposure, travel history to TB prevalent areas, working in healthcare settings, having HIV, or undergoing immune-weakening treatments.

TB is transmitted through the air via coughing. Symptoms include persistent cough, chest pain, weight loss, fatigue, fever, chills, and night sweats. Latent TB does not spread to others. Diagnostic tests include skin tests, blood tests, chest X-rays, and sputum samples.

TB is treatable with antibiotics, with costs and side effects varying. For more details, reach out to Brintnell Pharmacy and Travel Clinic.

Preventive measures for TB include education, early detection, maintaining good hygiene, and proper ventilation. Canada’s public health system effectively manages TB cases to prevent further spread of the disease.

During the initial visit for the TB skin test, tuberculin is injected under the skin. A follow-up visit is needed to assess the reaction.

Two to three days after the test, the bump at the injection site is measured to determine the result. If readings are delayed, repeat tests may be necessary.

Most individuals, including infants and those with negative or unknown TB skin test results, can undergo the procedure. If there was a severe reaction previously, consult your healthcare provider to discuss alternative options. Consider a TB blood test if needed, especially after receiving the BCG vaccine. Two-step skin tests can help differentiate old infections from recent ones.

Proper training is vital for conducting and interpreting TB skin tests. Consult healthcare providers experienced in this procedure. The CDC recommends TB blood tests in most cases, with skin tests as an alternative.

All individuals with active or suspected TB disease should be reported to the local health department. Some regions require reporting of latent TB infection. Contact your state TB program to learn about the specific requirements in your area.
