摘要： The present invention relates to a device for determining an analyte in a fluid sample in an assay. The device comprises a lid having a plurality of elements and a membrane. The elements have openings which allow passage of fluid to the membrane. The membrane is supported by the lid and covers the openings of the elements. The undersurface of the membrane is in contact with a porous wick which contains a first zone which includes binder attached to a particulate label and a second zone containing salt. The wick extends downward from the membrane and is in contact with the fluid sample.
