Rapid diagnostic device and assay

The invention claims (1) is a quick diagnostic device for detecting liquid test piece (9) is analyte (10) improved, and analysis method and multifunctional the reagent. The two steps analytic method using antithesis element and devices (1), wherein the device comprises a test unit are (2), and a liquid sample (9) wave filtering unit (3), and buffer solution (12). The testing unit (2) comprises is arranged on the target analyte (10) of the fossilization capture reagent bracket (6) reaction of (5), the supporting frame of (5) absorption area (4), and a reaction of (5) is a liquid blood optional separation region. The wave filtering unit (3) comprises to lift with dry pointer (8) mark area (7); the pointer is in the parsing process of with the testing unit (2) reaction of (5) of a liquid level of. The quick diagnostic analysis system for comparing to the input analyses, the number and method of said wherein analytical reagent and all the time of the analysis which is drop.
