Title:
TEST REAGENT PLATE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/179696
Kind Code:
A1
Abstract:
A biological sample rapid test reagent plate (100) and a preparation method therefor, and a method for promoting the release of a marker on a lateral flow test strip. The test reagent plate (100) comprises an upper cover (101), a lower plate (102), and a test strip (1) assembled between the upper cover (101) and the lower plate (102), wherein the test strip (1) comprises a sample pad (2), a marker combination pad (3), a test pad (4) and a water absorbing pad (5), which are sequentially stacked on one another and are all adhered to a bottom card (6); and the marker combination pad (3) is treated with a combination pad treatment solution in advance, and the combination pad treatment solution comprises saccharides, a polymer and a surfactant. By means of pre-treatment with the combination pad treatment solution, release of the marker on the test strip (1) can be effectively promoted, and the background of the test strip (1) after test is completed is clean, such that an operator can read a test result on the test pad (4) easily.
