Tuberculosis (TB) is a serious disease that can harm the lungs or other parts of the body, such as the brain, kidneys or spine. 

TB is spread through the air when someone who is sick with TB disease of the lungs coughs, sneezes, sings or speaks. Others can become infected by breathing the germs into their lungs. 

People who are infected with TB usually have had close contact with a person who is sick with TB disease. Family members, roommates, friends or close co-workers of people with TB disease are more likely to become infected. This is because they spend a lot of time in closed spaces (such as homes or offices) together. 

TB is NOT spread by shaking hands, kissing, sex, sharing glasses, plates, utensils, clothing, sheets or furniture. TB cannot spread through the air outside. 

There are medications to treat TB. TB can kill you if it is not treated. 

Who needs a tuberculosis test?

  • People who have recently arrived from a part of the world where TB is common (Asia, Africa, Caribbean, Mexico, Central and South America, Pacific Islands, Eastern Europe) 
  • People who are planning to spend more than 3 months in one of the areas of the world listed above. They should be tested before leaving on their trip and after returning. 
  • People who live or work in long term care or adult day care facilities 
  • People who the Health Department has determined to be in close contact with someone who has active TB disease 
  • People living with HIV/AIDS 
  • People who use street drugs 
  • Homeless people and staff who work in homeless shelters 
  • Inmates and people who work in jails. 

There are two tests that show if someone is infected with TB: 

  • TB skin test: For this test a small amount of test fluid is injected under the skin on the lower part of the arm. A trained health care worker must look at your arm for a reaction within 48 to 72 hours. Health care providers use this test most often. 
  • TB blood test: For this test, blood is drawn from the arm to measure the way the immune system reacts to TB bacteria.

What does it mean to have a positive TB skin test?

A positive TB skin test tells you if you have been exposed to TB germs. It does not tell you whether you are sick with active TB disease. If you have a positive TB skin test, you will need to have other tests done, like a chest X-ray and a sputum (mucus) sample to find out whether you have active TB disease. 

Can I get a TB skin test if I had BCG (Bacille Calmette-Guérin) vaccine?

Yes, people who have been vaccinated with BCG can still be given a TB skin test. BCG is a vaccine used to prevent TB disease in many countries. It is not generally recommended in the United States.
