There are two tests that can be used to help detect TB infection: 
TB skin test
The skin test is used most often A small needle is used to put some testing material, called tuberculin, under the skin In 2-3 days, the patient should return to the health care worker, who will check if there is a reaction to the test
TB blood test
In some cases, a TB blood test is used to test for TB infection This blood test measures how a person’s immune system reacts to the germs that cause TB
The drug resistance will be shown by a drug susceptibility test. To tell if someone has TB disease, other tests may be needed: 
Chest x-ray Sample of sputum (phlegm that is coughed up from deep in the lungs)
It is important to tell your health care provider if you have ever had a “positive” reaction to a TB skin test or TB blood test, or if you have been treated with TB drugs in the past.
