Principle of double antigen sandwich method
The doubleantigen sandwich method is based on the simultaneous binding of specific antigen and antibody on both sides of the virus,
which is less false positive from the reaction mechanism. It is not disturbed by rheumatoid factor and other factors, and its specificity is
higher than that of capture method and indirect method. At the same time, it can improve the detection sensitivity and is currently the best
method for detecting antibodies to Coronavirus disease.
Coronavirus disease rapid detection products
1. Novel Coronavirus 2019-nCoV Antibody Test (Up-converting Phosphor Immunochromatographic Technology)
Certificate NO.: National Medical Device Registration No. 20203400523
(1) Shorten the diagnostic window period and detect antibodies such as IgM and IgG at the same time;
(2) The double antigen sandwich method, in principle, ensures that the detection of the new crown antibody has higher sensitivity and specificity;
(3) Single test reagent, follow the test, no waste;
(4) Quickly complete the test in 15 minutes (value output);
(5) High detection sensitivity: no background interference, greatly improve the detection rate;
