his product is used to detect 2019 ncovigm/IgG antibody in human serum, plasma or whole blood. It is only used as a supplementary test indicator for suspected cases with a negative nucleic acid test for nCoV in 2019, or used together with nucleic acid testing for the diagnosis of suspected cases.
As a supplementary test indicator for suspected cases with a negative nucleic acid test for the new coronavirus, or used with nucleic acid testing for the diagnosis of suspected cases
Detection method
1. Preparation before experiment
Remove the reagents and samples and restore all reagents and samples to room temperature.
2. Experimental Steps
① Open the test reagent package, take out the test card and lay it flat.
② Add 10μL samples to the sample hole of the test card. Then add 2 drops (about 60μL) Sample buffer.
③ Reaction at room temperature, after 10-15 minutes, the test result can be read after 20 minutes and the result is invalid
④ Concise operating procedures
Open the package, take out the test paper, and place it horizontally

Detailed explanation of test results

Negative,Positive,Invalid
Diagram of the test results :
① Invalid result: if no red line is visible or only detection line (t line) and no quality control line (line C), the result is invalid, and it needs to be retested
② Negative result: if there is only red quality control line (line C), it means that there is no antibody in the sample or the antibody is lower than the detection level
③Positive result: if there are two red lines (one red quality control line and one red detection line) or three red lines (one red quality control line and two red detection lines), the result is positive
