Description

technical field

[0001] The invention relates to the technical field of in vitro diagnostic reagents, in particular to a kit for joint detection of 2019 novel coronavirus IgM and IgG antibodies and a preparation method thereof. Background technique

[0002] The 2019 novel coronavirus, or "COVID-19", was named by the World Health Organization on February 11, 2020. The new coronavirus belongs to the new coronavirus of the genus β, with an envelope, and the particles are round or oval, often pleomorphic, with a diameter of 60-140nm. The S protein is one of the main proteins of the virus, and its coding gene is used for virus typing. The N protein wraps the viral genome and can be used as a diagnostic antigen. Based on the current epidemiological investigation, its clinical manifestations: the incubation period is generally 3 to 7 days, and the longest does not exceed 21 days. The crowd is generally susceptible, with fever, fatigue, and dry cough as the main manifestations. A...
