The invention concerns an element for the determination of an analyte in a liquid by means of a specific binding reaction of two bioaffine binding partners containing in or on material which enables liquid transport between the zones. The element comprises a sample application zone; a detection zone located downstream thereof that is devoid of binding reagents and is the last zone on the element that allows liquid transport; a zone containing immobilized analyte or analyte analogue between the sample application zone and the detection zone; and impregnated conjugate that can be detached by liquid located in the sample application zone or upstream or downstream thereof composed of a bioaffine binding partner capable of a specific binding reaction with the analyte to be determined and a detectable label.
