Abstract
A diagnostic device for analysing properties of an analyte in a sample liquid including: a distribution zone having at least two hydrophilic layers placed one on top of the other, wherein one layer is a top layer (12) and the other is a bottom layer (13); and a detection zone located under the distribution zone, the detection zone having a detection layer (14), wherein: the top layer has one or more openings (15) through which the sample liquid is introduced into the device; the bottom layer having one or more openings (16) connecting the distribution zone to the detection zone; the bottom layer also having a means by which the sample liquid is distributed from the top layer's opening to the detection layer through the bottom layer's opening; and a visual indication results on the detection layer when the sample liquid comes into contact with the detection layer.
