The invention relates to a method and a device for the differential determination of a quantity of at least one analyte in a liquid sample. A te st strip which has at least two areas is used, these areas being composed in su ch a way that they can provide information about the quantity of the at least o ne analyte. The test strip also ensures that the sample or the portion of the sample flows laterally through the strip and the at least two areas by havin g a predetermined capacity for binding the at least one analyte in the first area. When this capacity is exceeded by a too great quantity of the at least one analyte, the at least one analyte is bound in at least one second area, the capacity of the second area being essentially equal to the capacity of t he first area and the binding of the at least one analyte in the at least one first area and the at least one second area being measured by a detectable property.
