AGLUTININ NEGATIVE

Stained bacterial suspensions
SLIDE AND TUBE TESTS

PRINCIPLE

The CROMATEST stained antigens are standardized suspensions of killed bacteria prepared for the detection and semi-quantitation by agglutination in either slide or tube tests of human serum agglutinins, a group of antibodies developed during some febrile infections such as brucellosis, salmonellosis and certain rickettsiosis.
