Zusammenfassung: | An immunoassay cassette 10, apparatus, and method for detecting an analyte in a liquid body-fluid sample are disclosed. The cassette 10 has a body 12 and a support mounted on the body 12, for movement toward and away from a sample transfer position. A sample supplied to a sample well 18 in the cassette body 12 is taken up by a reagent reservoir 24 containing a first reagent composition effective to react with one or more sample components to form a modified sample. The support 12 provides a reagent strip 30 having a transfer zone 32 that is brought into contact with the reservoir 24, when the support 14 is moved to its transfer position, a detection zone 34 located downstream of the transfer zone 32, and a second reagent composition effective to react with the modified sample to form a detectable analyte-dependent product. By controlling the movement of the support 14 toward and away from its transfer position, the volume and rate of sample flow from the reservoir 24 to the strip 30 can be controlled to optimize and/or standardize sample-transfer conditions in the assay.
