How is tuberculosis diagnosed?

A skin test can tell if you have TB.

You will have a small amount of non-infectious TB protein injected under your skin. This protein cannot spread the disease.

It can take 2 to 3 days for your skin to react to the injection for a positive result. If it is positive, you will need more tests to find out if you have the latent or active form of TB. This may include:

  • a medical examination
  • a chest X-ray
  • testing of some of your phlegm (thick liquid that comes up from your lungs or airways)

How is tuberculosis treated?

You can be cured by taking antibiotics.

It is important for you to take all of your antibiotics as prescribed to avoid:

  • spreading TB to others
  • increasing your risk of getting TB again, especially a type of the disease that is harder to treat
