Early diagnosis of streptococcal pharyngotonsillitis: assessment by latex particle agglutination test

Early diagnosis of streptococcal pharyngotonsillitis: assessment by latex particle agglutination test.

OBJECTIVES Acute pharyngitis is one of the most common diseases in pediatric practice, and the most common bacterial etiology is group A beta-hemolytic streptococcus (GABHS). Correct diagnosis and treatment are primarily of importance to the prevention of non-suppurative sequelae. Rapid tests for detecting the antigen of group A streptococcus are a useful tool for the diagnosis of streptococcal...

Rapid diagnosis of vaginal candidosis by latex particle agglutination.

Vaginal swabs from women who on clinical evidence were thought to have vaginal candidosis were examined for yeasts by conventional laboratory methods (microscopy and culture) and also assayed for Candida antigens using a rapid (3 min) slide latex particle agglutination tests. Results showed that a diagnosis of vaginal candidosis based on clinical criteria alone is unreliable: only half of the w...

Performance of Latex Agglutination Test (KAtex) In Diagnosis of Visceral Leishmaniasis in Iran

Background: Visceral leishmaniasis (VL) is an endemic disease in some parts of Iran. Many techniques have been used for diagnosis of VL, among which the urine based la-tex agglutination test (KAtex) is a promising one. Objective: To compare three diag-nostic tests of VL including KAtex, ELISA and Direct Agglutination Test (DAT) in VL patients and healthy controls in the south west of Iran. Meth...

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

Comparison of commercially available group B streptococcal latex agglutination assays.

Detection of group B streptococcus (GBS) antigen in urine by latex particle agglutination (LPA) may facilitate the rapid diagnosis of GBS sepsis. We sought to compare three commercial LPA assays with specimens that were spiked with type-specific antigen, group-specific antigen, or type III organisms. There were sensitivity differences between the assays, but the Bactigen assay performed best, d...
