Immunochromatography test strip for rapidly detecting lung cancer tumor markers and preparation method thereof

The invention discloses an immunochromatography test strip for rapidly detecting a lung cancer serum tumor marker and a preparation method thereof. The test strip comprises a bottom plate, and a sample pad, a gold label pad, an NC membrane and absorbent paper are sequentially arranged on the bottom plate; the NC membrane is adhered to the bottom plate, and a quality control line (C line), a cytokeratin 19 fragment detection line (T1 line) and a carcino-embryonic antigen detection line (T2 line) are sequentially arranged in the direction of the absorbent paper; the gold label pad and the sample pad are arranged at the lower end of the NC membrane, the absorbent paper is arranged at the upper end of the NC membrane, and the sample pad, the gold label pad, the NC membrane and the absorbent paper are overlapped. The test paper can rapidly realize simultaneous detection of cytokeratin 19 fragments (CYFRA21-1) and carcino-embryonic antigens (CEA) in whole blood, is simple and easy to operate, realizes visual result
