Profile: Lab21 Healthcare Ltd. focuses on clinical molecular diagnostic services and immunodiagnostic products for infectious diseases. Our Syphilis-RPR is a non-treponemal antibody test that detects plasma reagin antibodies. These antibodies tend to disappear after successful cure of the infection. Our RPR test uses carbon particles coated with cardiolipin antigen to detect anti-reagin antibodies in serum or plasma samples. This non-specific reaction is eliminated by suspension of the carbon particles in a formulated medium. These positive reactions are shown by macroscopic aggregation of the particles and can be read by eye. Our malaria EIA is used for the detection of antibodies. We provide anti A monoclonal, anti B monoclonal, anti A, B monoclonal, anti D IgG and IgM monoclonal, anti D IgM monoclonal, anti human globulin, bovine albumin 22% and bovine albumin 30%. We offer febrile antigens, which is supplied to identify and quantitate specific antibodies in human sera following infection with salmonellae, rickettsiae and brucellae pathogens. Our proteus OX2, OX19, and OXK suspensions are provided in the detection of rickettsial antibodies.
