Preparation method and application of anti-BPI-ANCA antibody test strip

The invention discloses an anti-BPI-ANCA antibody test strip, and a preparation method and application thereof. The test strip includes a sample pad (1), a combination pad (2), an analysis membrane (3), a water absorption pad (6), a base plate (7), a test zone T line (4) and a quality control C line (5). The upper part of the base plate (7) is adhered to the analysis membrane (3), and the the upper two ends of the analysis membrane (3) are respectively adhered to the combination pad (2) and the water absorption pad (6); one upper end of the combination pad (2) is adhered to the sample pad (1); the test zone T line (4) and the quality control C line (5) are arranged on the analysis membrane (3). The invention employs BPI-ANCA antigen protein to realize high sensitivity, high specificity and rapid detection of BPI-ANCA antibody in the sample and provide the basis for auxiliary diagnosis of clinical autoimmune diseases.
