Intended Use: This product is used for qualitative detection of neutralizing antibodies to 2019-nCoV in human serum/plasma.
Method: Enzyme-linked Immunosorbent Assay.
Sample Requirements: Serum sample, K2-EDTA anticoagulated plasma
- The negative/positive cutoff value of 2019-nCoV neutralizing antibody is judged by the inhibition rate. Inhibition rate = (1 - sample OD value/ negative quality control OD value) × 100%
- Inhibition rate ≥ 20% is positive, which means that the 2019-nCoV neutralizing antibody is detected;
- Inhibition rate <20 is negative, which means that the 2019-nCoV neutralizing antibody is not detected.
