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 ...
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]
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 ...
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.
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.
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.
According to a 2021 study, at-home antigen test Flowflex had a 100% accuracy in negative test results and 93% in positive results. BinaxNOW antigen tests had a sensitivity of 92.6% for symptomatic ...
Lymphocyte function-associated antigen 1 (LFA-1) is an integrin found on lymphocytes and other leukocytes. [1] LFA-1 plays a key role in emigration, which is the process by which leukocytes leave the bloodstream to enter the tissues. LFA-1 also mediates firm arrest of leukocytes. [2]
