Abstract:
1. Analyte detection method for the detection of at least one analyte in a sample, comprising the steps of (i) vertically positioning a test device, wherein said test device comprises on one or more sides of the solid support arranged from one end to the other end of the device: wherein said sample application zone, said non-capillary zone and said intermediate zone are disposed in a manner such that when the device is in use, sample can flow only by gravity through the non-capillary zone, from the first capillary zone comprising the sample application zone to the second capillary zone comprising the intermediate zone and detection zone, (ii) contacting the sample application zone on the top end of the device with a sample and (iii) allowing the sample to move from said first capillary zone comprising the sample application zone to said second capillary zone comprising the intermediate zone, by gravity through said non-capillary zone, and (iv) detecting the analyte, and wherein steps (i) to (iv) are performed with the device held in a substantially upright position.
