A lateral flow quantitative assay method capable of quantitatively determiningnthe concentration and analyzing the spatial distribution of a disease marker bynemploying the principle of the laser-induced fluorescence detection technique, whichnis based on detecting emitted fluorescence when laser light is focused to the diseasenmarker deposited onto a lateral flow quantitative assay chip. The present inventionndiscloses a strip, a laser-induced epifluorescence detection device and a small scannernfor the assay method. The present assay method is advantageous in terms of allowingnquantitative point-of-care diagnostics in hospitals, being capable of specificallyndetecting a disease marker by optimizing a lateral flow assay biochip for diagnosis ofna specific disease, allowing more accurate quantitative analysis of analytes, and beingncapable of simultaneously analyzing several cancer markers, reducing the hook effectnand expanding the detection range and accurately measuring concentration of analytes. |
