OBJECTIVE To evaluate the performance of serological tests using dried blood on filter-papers (micro-card agglutination test for trypanosomiasis (micro-CATT)) performed under field and laboratory conditions and using whole blood ((CATT/T.b. gambiense) (wb-CATT) and latex agglutination (LATEX/T.b. gambiense) (wb-LATEX)) for the serodiagnosis and surveillance of human African trypanosomiasis in W...
In their paper entitled "Comparison of the PREMIER Cryptococcal Antigen Enzyme Immunoassay and the Latex Agglutination Assay for Detection of Cryptococcal Antigens" (1), Gade et al. compare a new enzyme immunoassay (EIA) for the detection and quantification of circulating capsular polysaccharide antigen from Cryptococcus neoformans with the latex agglutination (LA) test performed with a commerc...
Latex agglutination by use of the Pneumoslide test on clinical blood cultures detected 22 Streptococcus pneumoniae strains as the etiological agents in 47 streptococcal septic episodes. The other 25 isolates were identified as viridans streptococci or streptococci of groups A, B, D, or G. The test demonstrated 100% sensitivity, 92% specificity, and predictive values for positive and negative re...
Cross-reactivity between Legionella spp. and Capnocytophaga ochracea was noted by latex agglutination tests (Serobact Legionella; Disposable Products, Adelaide, Australia). Four of 11 (36%) C. ochracea isolates agglutinated with latex reagents designed to identify Legionella pneumophila serogroups. C. ochracea isolated on buffered charcoal yeast extract media may give false-positive results in ...
The latex-fixation test (Singer and Plotz, 1956) is widely used as a serological criterion for rheumatoid arthritis (Alexander and McCarthy, 1966; Walton, 1968). The test is often carried out in serial dilution, by which a titre as well as an agglutination pattern is obtained. The usual practice is to choose a borderline titre in an empirical way and to call all titres above the borderline valu...
In correlating results obtained from a new latex-Rickettsia rickettsii test with results obtained from a reference microimmunofluorescence test for Rocky Mountain spotted fever, we found that for seropositive patients each microimmunofluorescence titer (up to 4,096) was usually double the median titer obtained from the latex-R. rickettsii test. The pattern of immunoserological response indicate...
The usefulness of serial study of C reactive protein in the early detection of neonatal septicaemia was evaluated in a neonatal unit using a commercially available latex agglutination slide test as a rapid screening method and electroimmunoassay as a reference method for C reactive protein determination. A positive latex test was obtained in 11 infants with verified septicaemia (positive blood ...
