Description
JOYSBIO’s coronavirus Ag test kit was independently evaluated at Centro Diagnostico Delta S.r.l. in Italy. A total of 78 positive specimens were tested with JOYSBIO’s COVID-19 Antigen Rapid Test Kit. These specimens were collected from patients who are suspected of COVID-19 with nasal swabs. The coronavirus antigen test kit’s sensitivity and specificity are compared against a CE-IVD marked RT-PCR test kit. This clinical evaluation is conducted under the assumption that SARS-CoV is no longer spreading in the community.
According to the clinical analysis of 190 samples, the detection sensitivity is 98.72%, and the specificity is 97.32%.
- Positive Percent Agreement (PPA) = 77/78(98.72%)(95%CI: 93.0%~100.0%)
- Negative Percent Agreement (NPA) = 109/112(97.32%)(95%CI:92.4%~99.4%)
- Accuracy = (77+109)/190×100% = 97.89%
- Kappa = 2×(77×109-3×1)/(80 ×112+78 ×110) = 0.96＞0.5
The limit of detection (LOD) of this product is 1.6 x 102 TCID50/mL, calculated through a gradient dilution method.
