Abstract
The present invention provides a device and a process for detecting an analyte in a biological fluid. That device comprises a cover portion with a restricted area for sample application, a separation matrix for separation of the analyte from substances in the sample that can interfere with detection of the analyte and means for detecting the analyte. The restricted area of sample application is less than 90 percent of the cross sectional area of the separation matrix and the separation matrix and the means for detecting analyte are under compression of between 14 to 43 percent. A process comprises applying a sample of fluid to such a device and detecting a signal generated from an interaction between the analyte and the detection means in the device.
