Getting a TB Test at the Health Department

What is a TB Test?

A tuberculosis (TB) test is a test that checks whether or not a person has been infected with the bacteria that causes TB. The test can be done using a blood sample or by injecting a small amount of protein under the skin. The protein used in the TB test is called tuberculin. If a person has been exposed to the TB bacteria, their immune system will produce a reaction to the tuberculin.

Why Do People Need to Get a TB Test?

People may need to get a TB test for a variety of reasons. For example, if someone has been in close contact with a person who has active TB disease, they may need to get tested to see if they have been infected. Additionally, people who have weakened immune systems, such as those with HIV, are at higher risk for developing TB and may need to get tested regularly. Finally, healthcare workers may need to get tested periodically to ensure that they are not infected with TB.

How to Prepare for a TB Test

There is no special preparation required for a TB test. However, it is important to tell your healthcare provider if you have had a previous positive TB test or if you have ever received the BCG vaccine for TB. These factors can affect the interpretation of the test results.

What Happens During a TB Test?

During a TB test, a small amount of tuberculin is injected under the skin, usually on the forearm. The injection site is then checked 2-3 days later to see if there is a reaction. If there is a reaction, the size of the reaction is measured to determine if the test is positive or negative.

Types of TB Tests

The two most common types of TB tests are the Mantoux test and the interferon-gamma release assay (IGRA) test. The Mantoux test involves injecting tuberculin under the skin and checking for a reaction 2-3 days later. The IGRA test is a blood test that checks for the presence of proteins that are produced by the immune system in response to the TB bacteria.

Interpreting TB Test Results

The interpretation of TB test results depends on the size of the reaction and the person's risk factors for TB. A positive TB test means that a person has been infected with the TB bacteria. However, it does not necessarily mean that the person has active TB disease. Further testing, such as a chest x-ray, may be needed to determine if the person has active TB.

What Happens If the TB Test Is Positive?

If a TB test is positive, further testing will be done to determine if the person has active TB disease. This may involve a chest x-ray and sputum sample testing. If the person does have active TB disease, they will need to undergo treatment with antibiotics. It is important to start treatment as soon as possible to prevent the spread of the disease to others.

How Is TB Treated?

TB is treated with a combination of antibiotics taken over a period of several months. It is important to take all of the prescribed medication, even if you start feeling better before the medication is finished. Failure to complete the full course of treatment can lead to the development of drug-resistant TB, which is much more difficult to treat.

Preventing the Spread of TB

To prevent the spread of TB, people with active TB disease should stay home and avoid close contact with others until they are no longer contagious. Additionally, people who have been exposed to TB should be tested and, if necessary, treated to prevent the development of active TB disease.

Getting a TB Test at the Health Department

TB tests are available at most health departments and clinics. The cost of the test may vary depending on your location and insurance coverage. It is important to get tested if you are at risk for TB or have been in close contact with someone who has active TB disease. Getting tested and treated early can help prevent the spread of TB and ensure that you receive appropriate care.
