The invention relates to an annular
gene-oriented paper micro-fluidic
chip detection card for rapidly screening chronic
obstructive pneumonia at an early stage and a test strip of the detection card.The detection card comprises an upper clamping cover and a lower clamping cover; the upper clamping cover is arranged on the lower clamping cover; a test strip groove is formed in the inner surface ofthe lower clamping cover; a test strip is arranged in the test strip groove; the test strip comprises a PVC bottom plate as well as a sample pad, a gold labeled pad, a
nitrocellulose membrane and a sample absorption pad which are sequentially in
lap joint with the PVC bottom plate. The test strip disclosed by the invention has the advantages of strong specificity and high sensitivity. According to the detection card and the test strip of the invention, widely applied and high-efficiency base
complementation and compound binding reactions are adopted to perform detection, and therefore, the level of proteins in a blood sample can be accurately detected; and a high-quality
gene probe and a compound are combined so as to realize capture, so that the sensitivity of the
nucleic acid detectiontest strip is greatly improved.
