INTRODUCTION

COVID-19 caused by SARS-CoV-2 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue, and dry cough. Nasal congestion, runny nose, sore throat, myalgia, and diarrhea are found in a few cases. The SARS CoV-2 IgG/IgM Rapid Test Kit is a lateral flow chromatographic immunoassay for the qualitative detection of IgM/IgG anti- SARS-CoV-2 in human serum, plasma or whole blood.

PRINCIPLE

The SARS CoV-2 IgM/IgG Rapid Test is a lateral flow chromatographic immunoassay. The test cassette consists of: 1)  a burgundy colored conjugate pad containing SARS-COV-2 Nucleocapsid protein and Spike  protein conjugated with colloid gold (SARS CoV-2 conjugates) and mouse IgG-gold conjugates, 2) a nitrocellulose membrane strip containing two test bands (M and G bands) and a control band (C band). The M band is pre-coated with monoclonal anti-human  IgM antibody for the detection of IgM anti- SARS CoV-2, G band is pre-coated with monoclonal anti-human IgG antibody for the detection of IgG anti- SARS CoV-2, and the C band is pre-coated with goat anti mouse IgG.
