What are the tests for Tuberculosis?

• Skin test: With a needle, a small amount of liquid is put under your skin on the lower part of your arm. After 2 or 3 days, if you have a hard bump on your arm, your doctor will measure the bump and tell you if your test is positive or negative. If your test is positive, you most likely have TB germs.

If your skin test is positive, these tests will be done to see if you have TB disease: 

• Test of your phlegm coughed up from your lungs
• Chest x-ray

TB can be found in other parts of your body besides your lungs. So you may have other tests too.
