Abstract

The invention discloses a colloidal gold immunochromatography device for combined detection of a novel coronavirus COVID-19 antigen and antibody and a use method thereof. Through simultaneously detecting a novel coronavirus COVID-19 antigen and a specific IgM antibody and IgG antibody thereof, the immunology reaction state of the organism can be accurately judged, so that an accurate detection result is given according to the detection result, the detection rate of the new coronavirus is improved, a false negative result is avoided, missing detection is prevented, the detection accuracy is further improved, and help is provided for clinical diagnosis and treatment of the new coronavirus pneumonia. The colloidal gold immunochromatography device is high in specificity, high in detection speed and easy and convenient to operate, does not need special equipment or operation of professionals, and can be applied to preliminary screening of various places such as communities, primary hospitals, airports, customs and even families.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a colloidal gold immunochromatographic device for joint detection of novel coronavirus COVID-19 antigen and antibody and its application method. Background technique [0002] In mid-December 2019, atypical pneumonia of unknown etiology was first discovered in Wuhan, China, and scientific research showed that it was caused by a new type of coronavirus, COVID-19. Pneumonia caused by the novel coronavirus COVID-19 is mainly characterized by fever, fatigue, and dry cough, and a small number of patients are accompanied by upper respiratory and gastrointestinal symptoms such as nasal congestion, runny nose, and diarrhea. Severe cases often develop dyspnea one week later, and severe cases rapidly progress to acute respiratory distress syndrome, septic shock, difficult-to-correct metabolic acidosis, and coagulation dysfunction. So far, there is no specific drug for COVID-19...
