In June 2020, JOYSBIO Biotechnology proudly released a new COVID-19 Antigen Rapid Test Kit (Colloidal Gold). The new coronavirus antigen test kit is a lateral flow immunoassay for the qualitative detection of SARS-COV-2 antigen (nucleocapsid protein) in upper respiratory samples with nasal swabs or saliva during the acute phase of infection. 


  • 15-minute rapid detection
  • Easy-to-operate coronavirus antigen test
  • Less-invasive nasal (NS) swab sample collection
  • CE-IVD marked
  • 20 tests per box
  • Nasopharyngeal swab and saliva versions available

Performance Characteristics

JOYSBIO’s coronavirus Ag test kit was independently evaluated at Centro Diagnostico Delta S.r.l. in Italy between October 2020 and January 2021. A total of 107 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 492 samples, the detection sensitivity is 98.13%, and the specificity is 99.22%.

  • Positive Percent Agreement (PPA) = 105/107 (98.13%) (95%CI: 93.4%~99.8%)

  • Negative Percent Agreement (NPA) = 382/385 (99.22%) (95%CI:97.7%~99.8%)

  • Accuracy = (105+382)/492×100%=98.98%

  • Kappa = 2×(105×382-3×2)/(108×385+107 ×384) = 0.97>0.5

The limit of detection (LOD) of this product is 1.6 x 102 TCID50/mL, calculated through a gradient dilution method.
