Syphilis
RPR: a fast, reliable and robust assay for the detection of non treponemal rapid plasma reagin antibodies in human serum or plasma. The test consists of modified VDRL antigen containing microparticulate carbon which aggregates in the presence of reagin type antibodies, indicating a positive result which can be read macroscopically.
TPHA: a fast, reliable and robust haemagglutination assay for detection of treponemal antibodies in human serum and plasma. TPHA uses preserved avian erythrocytes coated with antigens of T. pallidum (Nichols strain), which will bind with specific antibody present in patient’s serum or plasma. High flexibility is achieved with wide range of kit sizes available including a specially configured kit for use on the Beckman Coulter PK7200 and 7300.
Total Antibody EIA: a one step sandwich assay with with 60 minutes total incubation and the highest sensitivity and specificity in class as determined by MHRA. The assay is a total antibody assay (IgA, IgG, IgM) for detection during all stages of infection and features colour coded reagents for visual and automated addition verification.
IgM EIA: is a fast and specific two step capture EIA for detection of T.pallidum specific IgM for early stage diagnosis. The assay features a 2 hour assay time with no pre-assay sample dilution required, and specially formulated recombinant antigens to enhance reactivity and produce consistent and reproducible performance.

Malaria
Malaria Total Antibody EIA: a two-step sandwich assay with high sensitivity and specificity for effective screening of malaria-risk blood donors. A total antibody assay (IgG, IgM, IgA), the test detects all four Plasmodium species providing an effective screen and therefore shortening the deferral period for donors returning from malarial regions.

CMV
CMV Total Antibody EIA: a highly sensitive and specific screening assay for the detection of IgM, IgG and IgA antibodies in serum or plasma. Based on a microplate format, the assay is a one-step EIA with a dual sample-conjugate incubation phase, reducing the running time to less than 2 hours. A full sample/reagent verification system enables both visual and automated addition verification, providing maximum traceability for operators. The test is also highly sensitive, detecting seroconversion up to 17 days earlier than existing assays.

CMV Total Antibody HA: an automated screening assay for the detection of IgG, IgM and IgA antibodies in serum or plasma. Developed specifically for automated use on the Beckman Coulter PK7200/PK7300 analysers, this haemagglutination assay uses preserved avian erythrocytes coated with native CMV antigens which will bind with specific antibody present in patient’s serum or plasma. The cells are suspended in a medium containing components to eliminate non-specific reactions.

Chagas
Chagas Total Antibody EIA: a highly specific and sensitive screening assay for the detection of antibodies to Trypanosoma cruzi. The test is a solid phase immunoassay using whole extracts of Trypanosoma cruzi strains Tulahuen and Mn, including the highly immunogenic membrane antigens.
It also boasts a full sample/reagent verification system enables both visual and automated addition verification, providing maximum traceability for operators.

Blood Grouping
ABO: a range of both CE marked and non CE marked monoclonal reagents for ABO group determination.
Rhesus System: both CE and non CE marked reagents for Rhesus system determinations.
