  2. Diagnosis of tuberculosis - Wikipedia

    en.wikipedia.org/wiki/Diagnosis_of_tuberculosis

    Nucleic acid amplification tests (NAAT) for TB are a heterogeneous group of tests that use either the polymerase chain reaction (PCR) technique or transcription-mediated amplification (TMA) or other forms of nucleic acid amplification methods to detect mycobacterial nucleic acid. These tests vary in which nucleic acid sequence they detect and ...

    en.wikipedia.org/wiki/GeneXpert_MTB/RIF

    The Xpert MTB/RIF is a cartridge-based nucleic acid amplification test (NAAT) for rapid tuberculosis diagnosis and rapid antibiotic sensitivity test.It is an automated diagnostic test that can identify Mycobacterium tuberculosis (MTB) DNA and resistance to rifampicin (RIF).

  4. Nucleic acid test - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_test

    Rotavirus. A nucleic acid test (NAT) is a technique used to detect a particular nucleic acid sequence and thus usually to detect and identify a particular species or subspecies of organism, often a virus or bacterium that acts as a pathogen in blood, tissue, urine, etc. NATs differ from other tests in that they detect genetic materials (RNA or DNA) rather than antigens or antibodies.

    Nucleic acid amplification tests and adenosine deaminase testing may allow rapid diagnosis of TB. [100] Blood tests to detect antibodies are not specific or sensitive , so they are not recommended. [ 107 ]

  6. Mantoux test - Wikipedia

    en.wikipedia.org/wiki/Mantoux_test

    It is one of the major tuberculin skin tests used around the world, largely replacing multiple-puncture tests such as the tine test. The Heaf test, a form of tine test, was used until 2005 in the UK, when it was replaced by the Mantoux test. The Mantoux test is endorsed by the American Thoracic Society and Centers for Disease Control and ...

    en.wikipedia.org/wiki/Tuberculous_lymphadenitis

    A positive acid-fast bacteria (AFB) stain can support the diagnosis. [1] Other possible methods include nucleic acid amplification tests, fine needle aspiration (FNA), or excisional biopsy, the most invasive method. [1] Supplementary studies to aid in diagnosis include tuberculin skin tests, interferon-gamma release assays, or chest X-rays. [1]

  8. Tine test - Wikipedia

    en.wikipedia.org/wiki/Tine_test

    The tine test is a multiple-puncture tuberculin skin test used to aid in the medical diagnosis of tuberculosis (TB). The tine test is similar to the Heaf test, although the Mantoux test is usually used instead. There are various forms of the tine tests which usually fall into two categories: the old tine test (OT) and the purified protein ...

  9. Heaf test - Wikipedia

    en.wikipedia.org/wiki/Heaf_test

    The Heaf test, a diagnostic skin test, was long performed to determine whether or not children had been exposed to tuberculosis infection. The test was named after F. R. G. Heaf . Also known as the Sterneedle test , [ 1 ] it was administered by a Heaf gun (trademarked "Sterneedle"), [ 2 ] a spring-loaded instrument with six needles arranged in ...
