Colloidal gold diagnostic test paper for influenza A virus and preparation method thereof

Abstract

The invention relates to a colloidal gold diagnostic test paper for influenza A virus and a preparation method thereof for effectively solving such problems in the prior art as low testing sensitivity, low accuracy rate, and high missing detection rate. According to the technical scheme, the test paper comprises a test paper shell and a test paper strip, wherein the test paper strip is arranged in the test paper shell, the test paper strip is composed of a sample pad, a colloidal gold pad, a reaction membrane and a backing, the reaction membrane is adhered to the middle part of the backing, a detection line and a control line are sprayed on the reaction membrane, a water absorption pad is adhered to the tail part of the backing, one end of the water absorption pad is pressed on one end of the reaction membrane, the colloidal gold pad is adhered to the upper part of the backing, one end of the colloidal gold pad is pressed on the other end of the reaction membrane, the sample pad is adhered to the head part of the backing, close to one end of the colloidal gold pad, and one end of the sample pad is pressed on the other end of the colloidal gold pad. The colloidal gold diagnostic test paper for influenza A virus has the advantages of good testing sensitivity, high accuracy rate and low missing detection rate, and is innovation in the field of influenza A virus test paper.

Description

technical field [0001] The invention relates to a detection test paper, in particular to a colloidal gold diagnostic detection test paper for influenza A virus and a preparation method thereof. Background technique [0002] Influenza, referred to as influenza, is a common acute respiratory infectious disease caused by influenza virus. It is more common in winter and spring. Clinically, it is characterized by severe systemic poisoning symptoms such as high fever, fatigue, headache, and body aches, and mild respiratory symptoms. According to the data released by the World Health Organization in 2002, it is estimated that there are 600 million to 1.2 billion influenza cases worldwide every year. From the beginning of the last century to the present, there have been six global influenza pandemics, namely the "Spanish flu" in 1918, the "Asian flu" in 1957, the "Hong Kong flu" in 1968, the "Russian flu" in 1977, and the 1999-2000 The European influenza pandemic events in 2009 and...
