There are currently 7 types of human coronaviruses (HCoV) that can cause human respiratory diseases: HCoV-229E, HCoV-OC43, SARS-CoV, HCoV-NL63, HcoV-HKU1, MERS-CoV, and new coronavirus (SARS-COV-2), they are important pathogens of human respiratory infections. Among them, the clinical manifestations of the new coronavirus (SARS-COV-2) are systemic symptoms such as fever and fatigue, accompanied by dry cough, dyspnea, etc., which can rapidly develop into severe pneumonia, respiratory failure, acute respiratory distress syndrome, septic shock, and multiple organs Functional failure, severe acid-base metabolism disorder, etc., even life-threatening.
The vaccines manufactured in China include five technical routes including inactivated vaccines, recombinant protein vaccines, adenovirus vector vaccines, attenuated influenza virus vector vaccines, and nucleic acid vaccines. At present, a number of domestic vaccines, including the Sinopharm China Bio-New Coronavirus Inactivated Vaccine, have begun clinical trials and marketed emergency use.
SARS-COV-2 Neutralizing Antibody Test Kit (Colloidal Gold) (hereinafter referred to as the kit) developed by Shijiazhuang Hipro Biotechnology Co., Ltd is a kit based on nitrocellulose membrane and qualitative immunoassay. It is used to detect new corona virus-neutralizing antibodies in human whole blood, plasma, and serum. This test uses the test kit and clinical diagnosis results to analyze the data of the comparative test of clinical samples to verify the effectiveness of the kit.
This kit is based on nitrocellulose membrane and qualitative immunoassay used to detect the new coronavirus (SARS-COV-2) neutralizing antibody in human whole blood, plasma, and serum.
During the test, after adding human whole blood, plasma, and serum samples into the sample wells, it will react with the RBD protein-coated gold nanoparticles bound to the gold label pad to form a neutralizing antibody-RBD complex. The complex migrates forward along the test strip on the chromatographic membrane, and cannot interact and bind with the fixed ACE2 protein, and the T line will appear color.
If the specimen contains neutralizing antibodies to the novel coronavirus (SARS-COV-2), a color line will not appear in the test line area, indicating that the result is positive.
In order to determine the validity of the test strip, a color line will always appear in the control line area, indicating that an appropriate volume of sample has been added and reacted with the quality control antibody on the membrane.
If the quality control line C does not appear, it indicates that the test result is invalid, and this sample needs to be tested again with another test card.
