General Information

Tuberculosis (TB) is a disease caused by a bacterium called Mycobacterium tuberculosis. It spreads through the air when a person with active TB in their lungs or throat coughs, speaks, or sings. When this happens, tiny droplets containing TB germs are released into the air and can be inhaled by others nearby. TB most commonly affects the lungs, but it can also impact other parts of the body such as the brain, kidneys, or spine. In some cases, multiple areas of the body can be affected at the same time. 

There are two types of TB conditions:

· Inactive TB (also called Latent TB Infection): People with inactive TB have the TB bacteria in their bodies, but their immune system keeps it under control. They do not feel sick, have no symptoms, and cannot spread TB to others.

· Active TB Disease: This occurs when the TB bacteria become active because the immune system can't stop them from multiplying. People with active TB often feel sick and can spread the bacteria to others. Without treatment, active TB can be life-threatening.

Symptoms of Active TB may include:

· A cough lasting three weeks or more

· Chest pain

· Coughing up blood or mucus

· Fatigue or weakness

· Weight loss

· Loss of appetite

· Chills, fever, and night sweats

If you think you may have TB—or if you’ve been around someone who does—contact your healthcare provider or the public health department. TB can be diagnosed with a skin test or a blood test. Early detection and treatment are essential to stop the spread and protect your health.

The cost of a test is $20. After receiving the test, you will need to return 48-72 hours later to have the test read.
