The invention provides an assay device for quantification or detection of the presence or absence of an analyte in a liquid sample, comprising a molding (1) permanently or removably attached to a substantially planar plate (2) such that a part of said molding forms a capillary chamber (3) between said plate and the said molding, the device further comprising a chamber (5) into which a test sample and/or reagent can be introduced and further comprising a chamber (7) capable of accommodating an absorbent pad, wherein the said chamber into which a test sample and said chamber capable of holding an absorbent pad are in lateral flow contact via the said capillary chamber (3).
An assay device for quantification or detection of the presence or absence of an analyte in a liquid sample, comprising:
A method of forming an assay device comprising permanently or removably attaching a planar plate to an assembly such that a first sub-assembly of said assembly forms a planar capillary chamber between said plate and said assembly and participates in forming a sample receiving zone on one side of said capillary chamber, such that said sample receiving zone and said capillary chamber are in permanent fixed contact, the method further comprising slidingly attaching a second sub-assembly to the first sub-assembly, the second sub-assembly comprising a holder to accommodate an absorbent pad, whereby the holder of the second sub-assembly is moveable relative to the capillary chamber such that said holder can be moved in and out of contact with a second side of said capillary chamber.
A method of quantifying or detecting the presence or absence of an analyte in a liquid sample, comprising:
