What is the definitive test used to diagnose tuberculosis?
The TB skin test, also known as the Mantoux tuberculin skin test, is the most common way doctors diagnose tuberculosis. They’ll inject a tiny amount of fluid called tuberculin just below the skin in your forearm. It contains some inactive TB protein. You should feel a small prick from the needle.
What is the most accurate diagnostic test for active tuberculosis?

What is the rational drug used to treat tuberculosis?
Fluoroquinolones (FQs) have the potential to become an important component of a future TB treatment regimen, and drugs like moxifloxacin, ofloxacin and gatifloxacin are currently being evaluated in phase III clinical trials. The introduction of these agents could greatly influence global TB control efforts.
Which of the following diagnostic tests is endorsed by WHO for drug resistance pulmonary TB?
Xpert MTB/RIF (Cepheid, United States), a fast molecular-based test, is endorsed by WHO for the detection of the MTB complex and RIF resistance screening in suspected cases (WHO, 2017b). This test was first recommended in 2010 for the diagnosis of pulmonary TB in adults from sputum specimens.
Why is combination therapy used to treat TB disease?
When two or more drugs to which in vitro susceptibility has been demonstrated are given together, each helps prevent the emergence of tubercle bacilli resistant to the others. The standard of care for initiating treatment of TB disease is four-drug therapy.
What are the 2 types of tuberculosis?
There are two types of TB conditions: TB disease and latent TB infection.
How can you tell the difference between latent and active TB?
Persons with latent TB infection do not feel sick and do not have any symptoms. They are infected with M. tuberculosis, but do not have TB disease. The only sign of TB infection is a positive reaction to the tuberculin skin test or TB blood test.
What is DST culture?
Drug susceptibility testing (DST) of Mycobacterium tuberculosis is generally carried out after a culture is isolated from a clinical specimen. This takes a long time, first to isolate a culture and then to perform drug susceptibility testing (indirect DST).
What is the Genexpert test?
Introduction: Gene-Xpert, a CBNAAT (catridge based nucleic acid amplification test) is a widely accepted diagnostic test for Tuberculosis. This test is a rapid diagnostic test for Tuberculosis detection as well as Rifampicin resistance in direct smear negative cases.
What is the rational basis test?
The rational basis test is a judicial review test. A judicial review test is what courts use to determine the constitutionality of a statute or ordinance. The Requirements of the Test
Why should I get tested for tuberculosis (TB)?

When is a culture done to confirm the diagnosis of tuberculosis (TB)?
Therefore, a culture is done on all initial samples to confirm the diagnosis. (However, a positive culture is not always necessary to begin or continue treatment for TB.) A positive culture for M. tuberculosis confirms the diagnosis of TB disease. Culture examinations should be completed on all specimens, regardless of AFB smear results.
What is a complete medical evaluation for tuberculosis (TB)?
A complete medical evaluation for TB includes the following: 1 Medical History. 2 Physical Examination. 3 Test for TB Infection. 4 Chest Radiograph. 5 Diagnostic Microbiology. 6 (more items)
