Abstract

The invention provides a kit for detecting a novel coronavirus SARS-CoV-2 antibody. The kit comprises magnetic particles coated with an SARS-CoV-2 antigen, an anti-human IgM / IgG secondary antibody labeled by a chemiluminescent marker, and a non-novel coronavirus antigen. By adopting the kit, whether a patient sample to be detected contains a specific IgM / IgG antibody generated by infection of the novel coronavirus SARS-CoV-2 or not can be specifically detected, and the specific IgM / IgG antibody does not generate cross reaction with influenza virus, common coronavirus and the like. The invention also provides a detection method of the novel coronavirus.

Description

technical field

[0001] The invention relates to the field of biomedical detection, in particular to a kit and method for detecting antibodies against novel coronavirus SARS-CoV-2. Background technique

[0002] The novel coronavirus (SARS-CoV-2) directly attacks the patient's respiratory system and digestive system, causing the patient's immune system to be disturbed, and in severe cases, an inflammatory storm will result in death.

[0003] One of the main reasons why the new coronavirus is so harmful is that patients have an incubation period of 3-14 days or even longer. Early patients do not have any symptoms, even if the widely accepted gold standard fluorescent quantitative PCR technology is used, the positive detection rate in the early stage of the disease is only 30-50%, making the diagnosis extremely difficult. Medical institutions have to use CT and clinical symptoms as supplementary means of nucleic acid testing, which not only costs a lot of money, takes a long ti...
