Febrile antigens are intended to be used for the qualitative and semi- quantitative detection of bacterial agglutinins in bacterial infection using slide or tube test technique.
corresponding homologous antigens causes agglutination under controlled conditions. The agglutination is macroscopically visible. For screening purposes, the antigens can be used in the qualitative rapid slide test. Positive results can be confirmed with the quantitative tube test to verify the antibody titer. the reagents.
ATLAS Febrile antigens can be used with serum stored 2 to 8º C. The test requires serum collected from 5-10 ml of whole blood sample. The serum should be separated quickly to avoid any excess hemolysis and should not be inactivated. It should also be clear and free from bacterial contamination. PROCEDURES 1. QUALITATIVE PROCEDURES
This panel comprises antibody testing for infections caused by Ricketssia rickettsii, Richetssia typhi, Salmonella, and Brucella in patients with fever. A 4-fold change in titers of antibodies between acute and convalescent sera confirms the infection.
qualitative and semi-quantitative detection of antibodies associated with febrile infections caused by typical flagellar or somatic bacteria (Salmonella typhi, S. paratyphi, Brucella, Proteus). The test can be performed as a rapid slide agglutination test and also as a tube agglutination test (Widal test).
Positive control for qualitative verification of Atlas Medical Febrile Antigen Test. INTRODUCTION & PRINCIPLES Antibodies are formed in human infection cases with various microbiological agents. Mixing these antibodies with the corresponding homologous antigens causes agglutination under controlled conditions.
20 wrz 2024 · “Febrile antigens are stained bacterial suspensions that can be used either as a screening test, (rapid slide agglutinating procedure) or as a confirmatory test (tube agglutination) to verify positive results found by the rapid slide method.”
