The 2019-nCoV Neutralization Antibody Test Kit (ELISA) is designed to measure the concentration of neutralizing antibodies to COVID-19.It is used for detection of Neutralization Antibodies.
Used for qualitative detection of neutralizing antibodies to 2019-nCoV in clinical samples (serum/plasma/ whole blood).
High sensitivity (98.61%)
High specificity (99.11%)
Enzyme-linked Immunosorbent Assay.
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.
