Covid-19 Antigen rapid test with nasal swab from Joysbio. 20 pcs per package.

In June 2020, JOYSBIO Biotechnology released a new COVID-19 Antigen Rapid Test Kit (colloidal gold). This coronavirus test kit is a lateral flow immunoassay for qualitative detection of SARS-COV-2 antigen (nucleoside protein) with upper respiratory tract samples taken with a nasal swab during the acute infection phase. The test is intended for professional use.

Clinical features and accuracy

Joysbio’s test kit for Coronavirus Ag has been evaluated at Centro Diagnostico Delta in Italy. A total of 190 samples were tested with Joysbio’s COVID-19 Antigen Rapid Test Kit. These samples were collected with a nasal swab, from patients 1-5 days after the onset of symptoms. The sensitivity and specificity of the coronavirus antigen test kit were compared with a CE-IVD-labeled / FDA EUA-approved RT-PCR test kit (BGI). This clinical evaluation was performed under the assumption that SARS-CoV is no longer spreading in society.

According to the clinical analysis of 190 samples compared to RT-PCR samples, the results for 1-5 days from symptom onset are as follows:

  • Sensitivity 98,72%
  • Specificity 97,32%
  • Average reliability 97,89%


What is the difference between Covid-19 RT-PCR test, Antigen test and Antibody test?

There are two types of tests available for COVID-19: viral test and antibody test. RT-PCR tests and antigen tests are both viral tests that detect the presence of SARS-CoV-2 from upper nasal samples. The RT-PCR test focuses on the genomic information (RNA) of the virus; however, the COVID-19 antigen test kit detects bits of proteins that make up the SARS-CoV-2 virus. The WHO recommends both RT-PCR tests and antigen tests for the diagnosis of active coronavirus infection.
