Automated immunoassay analyzer

摘要

An improved automated immunoassay analyzer including a high throughput automated immunoassay system which can perform high volume testing on a broad range of analytes while selecting from among a diverse set of immunoassays for any given sample. The immunoanalyzer has the capacity to perform a wide range of different types of immunoassays by facile storage and automated combination aboard the instrument among a wide variety of different types of reagents and heterogenous immunoassay beads stored on-board the instrument. The automated design allows reduced user interface (e.g., tests are performed automatically from computer input) including the ability to order, perform and reassay tests reflexively based on test results without operator intervention. Further, the inventive analyzer is not sample tube specific; that is, an instrument that can accept sample tube sizes within a broad size range. The inventive automated immunoassay analyzer also provides a re-useable sample dilution well, and a high speed bead washing station that eliminates the need for assay tubes having integral, waste fluid collection chambers.
