The operative site of an assay device is dosed with a controlled volume of a liquid specimen by a holding device which holds the controlled volume of specimen in contact with the operative site, although the holding device remains out of contact with the operative site. A sink device is in contact with the margin of the holding device and moves excess specimen away from the holding device. In one embodiment the device makes possible a non-wipe teststrip architecture. The device can be used in the detection of analytes including glucose or cholesterol in blood or urine and can be interrogated visually, optically or electrically, depending on the reagent used at the operative site.
