Everything You Need to Know About TB Tests and the Health Department
Tuberculosis (TB) is a highly contagious and potentially deadly disease that affects the lungs and other parts of the body. When a person is diagnosed with TB, it’s important to undergo the proper tests and treatments to prevent the spread of the disease. In this article, we’ll cover everything you need to know about TB tests and how the Health Department can help.
What is TB?
TB is caused by a bacterium called Mycobacterium tuberculosis. It spreads from person to person through the air when an infected person coughs, sneezes or talks. TB can affect the lungs, but it can also affect other parts of the body, such as the bones, joints, and kidneys. Symptoms of TB include a persistent cough, fever, fatigue, weight loss, and night sweats.
Why is it important to get tested for TB?
TB can be fatal if left untreated. It’s important to get tested early if you think you may have been exposed to TB. Testing is also important for those who have come into close contact with someone who has TB. If you are diagnosed with TB, you can receive treatment to cure the disease and prevent it from spreading to others.
How are TB tests conducted?
There are several types of tests that can be used to diagnose TB. The most common test is a skin test called the Mantoux tuberculin skin test, or TST. A small amount of tuberculin is injected into the skin of your forearm. After 48 to 72 hours, a healthcare provider will measure the size of the bump on your arm. If the bump is larger than a certain size, it may indicate that you have been exposed to TB.
Another test is the blood test called the Interferon Gamma Release Assay (IGRA). This test measures the amount of interferon-gamma released in response to TB antigens in the blood. Results of this test are typically available within a few days.
What happens if I test positive for TB?
If you test positive for TB, it means you have been exposed to the bacteria. However, it doesn’t necessarily mean that you have active TB disease. You may have latent TB infection (LTBI), which means the TB bacteria are present in your body but are inactive.
If you have LTBI, you may be prescribed medication to prevent the bacteria from becoming active and causing TB disease. If you have active TB disease, you will need to undergo treatment to cure the disease. Treatment typically involves a combination of antibiotics taken for several months.
How can the Health Department help?
The Health Department can help in several ways. They can provide TB testing, treatment, and education. They can also assist with contact tracing, which involves identifying people who may have been exposed to TB and monitoring them for symptoms. In addition, the Health Department can provide resources and support to those who have been diagnosed with TB to ensure they receive the care they need.
In conclusion, TB is a serious disease that can be prevented and treated with proper testing and treatment. If you think you may have been exposed to TB, it’s important to get tested and seek treatment if necessary. The Health Department can provide valuable assistance in this process, so don’t hesitate to reach out if you need help.
