Abstract: A device, method of use and method of manufacturing of said device for detecting an analyte in a biological fluid. The device comprises an immunochromatographic test strip with a raised, arcuate sample receiving zone. The test strip comprises a bibulous strip positioned above the base wherein the bibulous strip defines a developer receiving zone, a sample application zone and an indicator zone and wherein the zones are in capillary contact with each other permitting a developing fluid to wick from the developer receiving zone, through the sample application zone to the indicator zone. Further, a mobilizable detector agent attached to a marker for binding to an analyte of interest in a sample is positioned downstream from the sample application zone and upstream from an immobilized indicator agent, which is attached within the indicator zone.
