Abstract
The present invention relates to a liquid flow device, in particular a capillary testing device provided as a chip, comprising a second pathway which intersects the first pathway at a downstream point of convergence, so that the two pathways share an outlet and when liquid in the second pathway reaches the point of convergence, liquid flow in the first pathway stops. Means for measuring the distance travelled by liquid in the first pathway are provided to determine the extent of liquid flow and to enable correlation with the amount of analyte in the liquid.
