Key Assays for

Diagnostic Microbiology





ADVIA ® Centaur ™

HBsAg - a 29 minute assay offering a sensitivity of 0.01ng/mL. The ADVIA Centaur can also be set up for a hands free confirmatory assay or reflex to other HBV markers.

Anti-HBs - an 18 minute assay offering linear measurement between 1 and 1000 mIU/mL.

HBCoreTotal - an antigen bridging assay using a chaotrope to remove non specific binding has a specificity of 99.9% and a throughput of 120 tests per hour.

HBCoreIgM - an M antibody capture assay with a clinical specificity of 100% and a throughput of 120 tests per hour, the cut off point of this assay is designed to assist in the differentiation of acute and chronic HBV positive individuals.

HCV - this assay requires 10uL of serum or plasma and has a throughput of 120 tests an hour. The 99.9% specificity coupled with a high delta reduces the number of grey zone results which reduces laboratory costs and patient concerns.

HIV 1,2,O - this multi-epitope assay not only has excellent specificity and sensitivity but also has the ability to detect low affinity antibodies and seroconverters thanks to the architectural flexibility inherently allowed by the platform design.

Rubella IgG - a qualitative or quantitative assay utilising 10 uL serum or plasma with an assay range of 0.2 - 500 IU/mL.

Rubella IgM - an M antibody capture assay utilising 20 uL serum or plasma with a specificity of >99%.

Toxoplasma IgG - a qualitative or quantitative assay utilising 10 uL serum or plasma with an assay range of 0.5 - 700 IU/mL.

Toxoplasma IgM - an M antibody capture assay utilising 10 uL serum or plasma with a specificity of >99%.

Gentamicin - A quantitative assay utilising 15 uL serum or plasma with an assay range of 0.17 - 12 ug/mL.

Vancomycin - A quantitative assay utilising 40 uL serum or plasma with an assay range of 0.46 - 62 umol/L.

Tobramycin - A quantitative assay utilising 50 uL serum or plasma with an assay range of 0.18 - 13 ug/mL.

HAV Total, HAV IgM, HBeAb and HBeAg are in development

The immunoassay platform for these assays is the ADVIA® Centaur™ which was designed to offer maximum benefits for laboratories performing ID assays:

- Sample Integrity is provided by the use of single use sample pipettes which allow the safe use of primary samples.

- Sample and reagent verification technology guarantees results against short sampling, clots and bubbles.

- Sample Prioritisation is achieved by the use of a STAT port allowing the operator to manage urgent samples.

- User defined, in addition to instrument defined QC parameters allows you to set up an internal QC programme on the ADVIA® Centaur™ utilising Westgaard rules.
