  2. Cryptococcosis - Wikipedia

    en.wikipedia.org/wiki/Cryptococcosis

    Cerebrospinal fluid (CSF) or blood antigen testing by lateral flow assay for cryptococcal antigens has a sensitivity and specificity greater than 99% for cryptococcosis. [19] A CSF fungal culture can tell if there is a microbiological failure (failure of the fungal infections to treat the infection). CSF fungal culture has a 90% sensitivity and ...

  3. Cryptococcus neoformans - Wikipedia

    en.wikipedia.org/wiki/Cryptococcus_neoformans

    Cryptococcal antigen from cerebrospinal fluid is thought to be the best test for diagnosis of cryptococcal meningitis in terms of sensitivity, though it might be unreliable in HIV-positive patients. [12] The first genome sequence for a strain of C. neoformans (var. neoformans; now C. deneoformans) was published in 2005. [5]

  4. Latex fixation test - Wikipedia

    en.wikipedia.org/wiki/Latex_fixation_test

    A latex fixation test, also called a latex agglutination assay or test (LA assay or test), is an assay used clinically in the identification and typing of many important microorganisms. These tests use the patient's antigen - antibody immune response.

  5. Lumbar puncture - Wikipedia

    en.wikipedia.org/wiki/Lumbar_puncture

    The India ink test is still used for detection of meningitis caused by Cryptococcus neoformans, [37] [38] but the cryptococcal antigen (CrAg) test has a higher sensitivity. [ 39 ] Chemistry

  6. Hook effect - Wikipedia

    en.wikipedia.org/wiki/Hook_effect

    Illustration of the effects of excess antigen and blocking antibodies on immunoassays. In an agglutination test, a person's serum (which contains antibodies) is added to a test tube, which contains a particular antigen. If the antibodies interact with the antigen to form immune complexes, called agglutination, then the test is interpreted as ...

  7. Lateral flow test - Wikipedia

    en.wikipedia.org/wiki/Lateral_flow_test

    A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.

  8. Cryptococcus - Wikipedia

    en.wikipedia.org/wiki/Cryptococcus

    Cryptococcus is a genus of fungi in the family Cryptococcaceae that includes both yeasts and filamentous species. The filamentous, sexual forms or teleomorphs were formerly classified in the genus Filobasidiella , while Cryptococcus was reserved for the yeasts.
