摘要 |
The invention relates to a device for determining an analyte in a liquid sample. The inventive device consists of: a capillary action means (1), involving lateral migration, defining a reference capillary action direction and comprising a liquid sample deposit area (3) and an analyte-detection area (5) which is disposed downstream of the deposit area; a first analyte-specific binding reagent (4) which is conjugated to a visible and/or measurable marker and which is free to migrate when wet by means of capillary action in the above-mentioned capillary action means (1) along the reference direction; and a second analyte-specific binding reagent (6) which is immobilised in the detection area. The invention is characterised in that the detection area (5) comprises the analyte (7) or an analogue of the analyte, which is immobilised and disposed at a distance from the second specific binding reagent (6). |
