[INTENDED USE]
The product is suitable for qualitative detection of neutralizing antibodies (NAbs) against SARS-CoV-2 that block the interaction between the receptor binding domain (RBD) of the spike glycoprotein and the Angiotensin converting enzyme Ⅱ (ACE2) receptor. The device can be instrumental in vaccine and therapeutic development as it is suitable for all antibody isotypes. It may also help in current COVID-19 investigations of sero-prevalence, assessment of human immunity, longevity of protective immunity, efficacy of different vaccine candidates as well as tracking infection.
[PERFORMANCE CHARACTERISTICS]
Sensitivity
The sensitivity to S-mIgG1 neutralizing antibody can reach 2ug/mL.
Accuracy
A side-by-side comparison was conducted by the results of SARS-Cov-2 Neutralizing Antibody Test Device (Test Reagent) developed by Hangzhou Deangel Biological Engineering Co., Ltd. and cPassTM from Genscript CO., Ltd. 328 clinical specimens from Professional Point of Care site were evaluated, 105 were positive and others negative. Base on the results from the clinical studies, the statistical analysis was made as follows:
| | cPassTM | Total |
| Positive | Negative |
| Test reagent | Positive | 96 | 2 | 98 |
| Negative | 9 | 221 | 230 |
| Total | 105 | 223 | 328 |
For test reagent, the clinical sensitivity with the “Compared Reagent” was 91.4% (95% CI: 77.7%~100%), the clinical specificity was 99.1% (95% CI: 97.2%~100%), the coincidence rate was 96.6% (95% CI: 92.4%~100%).
