Detailed explanation-1: -Tuberculosis most commonly affects the lungs. Symptoms include productive cough, fever, weight loss, and malaise. Diagnosis is most often by sputum smear and culture and, when available, by nucleic acid amplification tests. Treatment is with multiple antimicrobial drugs given for at least 4 months.

Detailed explanation-2: -There are two kinds of tests used to detect TB bacteria in the body: the TB skin test (TST) and TB blood tests. A positive TB skin test or TB blood test only tells that a person has been infected with TB bacteria.

Detailed explanation-3: -WHO recommends rapid molecular diagnostic tests as initial tests for people showing signs and symptoms of TB. Other diagnostic tools can include sputum smear microscopy and chest X-rays. With TB infection, a person gets infected with TB bacteria that lie inactive in the body.

Detailed explanation-4: -The tuberculosis (TB) blood test, also called an Interferon Gamma Release Assay or IGRA, is a way to find out if you have TB germs in your body. The TB blood test can be done instead of a TB skin test (Mantoux).

Detailed explanation-5: -The first step in diagnosing TB is a skin or blood test. These will show if you have been exposed to the bacteria. For the skin test, or PPD, a substance called tuberculin is injected just under the skin on your forearm.
