Abstract:
1. A lateral flow, chromatography test device comprising: a base including two spaced lock members proximate a bottom edge; a lateral test strip secured onto the base and disposed between the lock members and the stopping mechanism; and a cover having a bottom edge flexibly formed with the bottom edge of the base and including a top recess for exposing a portion of a stopping mechanism in an inoperative position, a window located below the recess and above a portion of the test strip, and a well spaced from and laterally aligned with the window, whereby adding a sample solution through the well to the test strip, after passing a predetermined period of time; the stopping mechanism movably positioned on the base and including at least one leg at each of two sides, each leg having a latched end having a scraping member, and a member interconnecting both sides; wherein the scraping members of the stopping mechanism physically remove a portion of nitrocellulose on the test strip located in the passage of the scraping member movement; and whereby pushing the interconnecting member downward will cause the scraping members to further remove materials on the test strip below the latched ends until lockingly engage the latched ends with the lock members, thereby permanently stopping ongoing reactions on the test strip.
