    摘要: An immunoassay cassette, apparatus, and method for detecting an analyte in a liquid body-fluid sample are disclosed. The cassette has a body and a support mounted on the body, for movement relative to the body to first and second transfer positions. Sample supplied to a sample well in the cassette body is transferred to a reagent reservoir on the cassette body, by moving the support to its first transfer position. Here the sample reacts with a first reagent composition in the reservoir effective to form a modified sample. The modified sample is then transferred to a reagent strip on the support by moving the support to its second transfer position. The reagent strip has a transfer zone at which sample material is transferred to the strip, a second reagent composition effective to react with the modified sample to form a detectable analyte-dependent product, and a detection zone located downstream at which the detectable product can be observed. By controlling movement of the support to its first and second positions, the cassette can effectively handle a variety of samples having different flow rates.
