COMPETITIVE IMMUNOASSAY DEVICE |
摘要 |
A chromatographic assay device for detection and/or determination of an analyte in a competitive immunoassay gives a semiquantitative or quantitative indication of analyte concentration in a single assay device while also giving a positive indication that flow has occurred properly through the device. In one form, the device comprises a first opposable component (12) including a sample preparation zone (18) and an absorber (20); and a second opposable component (14) including a first chromatographic medium (22) with capture and detection zones, a second chromatographic medium (32) with a comparison zone (38), and a comparison label zone (40).
