Abstract

The present invention is directed to a method and device for monitoring and measuring agglutination within a sample using a lateral flow assay device. In particular, the present invention is directed to a method for monitoring and measuring the onset of agglutination within a sample on a lateral flow assay device comprising micro-projections to define a lateral flow assay path wherein the method comprises combining the sample with at least one detectable marker and at least one agglutination marker or a combination thereof to form a labelled sample; subjecting the labelled sample to lateral flow; and monitoring the redistribution of the agglutination marker through the lateral flow assay path as agglutination occurs. The invention is also directed to a lateral flow assay device for carrying out the method and a kit comprising the lateral flow assay device and detection means.
