    • Lateral flow assay devices comprising a multisite array of test sites (8) for measuring a biomolecule analyte (3) having a solid support (5) including absorbent material for providing capillary flow, one device being divided into parallel lanes (7) in the flow direction. The devices comprising a sample portion for receiving a sample; a diagnostic portion comprising a multisite array of test sites (8) each comprising a probe for the biomolecular analyte (3), wherein at each test site of the multisite array the conditions for the interaction between the biomolecular analyte and the probe can be varied independently; an absorbent portion of absorbent material for providing capillary flow; and electrodes (10) for actuating and controlling conditions. The sample portion, diagnostic portion, and absorbent portion are in capillary flow communication resulting in a capillary flow from sample portion towards absorbent portion, whereby the sample flows across the probe at each test site in the diagnostic portion to provide contact between the sample and such probe. Methods for measuring analyte concentration in a sample using such lateral flow assay devices.
