Comments
Vazyme has established independent process to ensure that variants are monitored in time. Each variant listed as “variant of concern” and “variant of interest” by World Health Organization (WHO) will be studied since the date of listing. And the study procedure is as follows:
Step one: In-silico analysis
Note: In in-silico analysis, the overlap of mutation site of new variant and the epitope of antibodies used in the test will be analyzed to identify potential impact on the performance of test kit.
Step two: Validation of Limit of Detection (LOD) in form of TCID50/mL, if necessary.
Step three:Clinical performance validation of Positive Percent Agreement (PPA), if necessary.
