An assay device, analytical instrument and assay method for determining the presence or amount of an analyte in a fluid is disclosed. The device is a one-step lateral flow dry reagent immunoassay with one, two or more zones along a transverse axis of the device, each zone can contain or be preceded by diffusively or non-diffusively bound reagents. The invention measures an indicator in one or two test zones for each analyte to determine its presence or concentration. The signal reagent (indicator) may be a particle such as a colored latex or colloidal gold. The assay quantitation may be read by an instrument.

Dry reagent strip configuration, composition and method for multiple analyte determination

The invention provides a filter for separating red blood cells from a whole blood sample to form plasma. The filter includes a solid phase support and an agglutinin for red blood cells. The agglutinin is insoluble in the whole blood sample and is immobilized on the solid phase support. The present invention also includes a device and method for determining the presence of at least one of a plurality of analytes in a sample of whole blood.

Device for blood separation in a diagnostic device

The present invention provides a filter for effectively removing substances from a sample of bodily fluid which can interfere with the results of an assay. The filter includes a solid phase support and an active chemical component for binding to the interfering substance. The active chemical component is insoluble in the sample and is immobilized on the solid phase support. The present invention also includes a filter device, transport matrix, assay device, and method for removing substances which interfere with determining the presence of one or more analytes in a sample.
