Listed by the German Federal Institute for Drugs and Medical Devices in the "List of Antigen Tests for Direct Pathogen Detection of Coronavirus SARS-CoV-2".
Manufacturer: JOINSTAR Biomedical Technology Co., Ltd
Sensitivity and Specificity
The COVID-19 antigen rapid test was tested with the leading commercial reagent (PCR) and the results showed that the COVID-19 test has high sensitivity and specificity.
The following 3 sampling options are available:
Saliva sample of the posterior oropharynx (mouth part of the pharynx).
Relative sensitivity: 90.00% (95%CI: 79.49% - 98.96%)
Relative specificity: 100.00% (95%CI: 88.43% - 100.00%)
Accuracy: 96.67% (95%CI: 86.05% - 97.51%)
Sputum sample (secretion of the deep airways that enters the throat during coughing)
Relative sensitivity: 95.00% (95%CI: 86.08% - 96.24%)
Relative specificity: 100.00% (95%CI: 88.43% - 100.00%)
Accuracy: 96.67% (95%CI: 90.57% - 99.31%)
Stool sample
Relative sensitivity: 95.00% (95%CI: 86.08% - 96.24%)
Relative specificity: 100.00% (95%CI: 88.43% - 100.00%)
Accuracy: 96.67% (95%CI: 90.57% - 99.31%)

Test Principle:
The novel coronavirus invades human cells through the specific binding of its spike glycoprotein (binding protein) to the ACE2- receptor located on the human cell membrane. In this assay, the ACE2 receptor was replaced by antibody to develop a novel binding protein receptor chromatography assay for the rapid detection of the novel coronavirus. In clinical practice, the test can be used for rapid detection of SARS- CoV-2 and all its mutations in saliva samples from the posterior oropharyngeal region, sputum and stool samples. The test takes only 15 minutes to perform and is much simpler than that of an RT-PCR test. The SARS-CoV-2 virus has been found to have evolved even more contagious mutations due to mutations in S1 proteins (such as D614G) that have stronger binding to ACE2 receptors. Given the principle of the test, which is based on the binding of ACE-2 receptors, the test should be able to detect such mutations as well.
The test kit contains a nitrocellulose membrane (NC) that has a coating of rabbit anti-S1- proteins of coronavirus in the test line region (T) and a coating of polyclonal goat anti-rabbit IgG- antibodies in the control region (C). The latex-labelled ACE2 protein and the latex-labelled rabbit IgG are embedded in the reagent pad.
To perform the assay, three drops of sample are added to the sample well and the sample flows upward by capillary action. After a 15-minute incubation period, the latex-labeled ACE2 protein is bound by the S1 protein of the virus and then captured by anti-S1 protein antibodies on the test line region if the sample contains the virus. If the sample does not contain the virus, then the latex-labeled ACE2 protein is not captured by the anti-S1 protein antibodies coated on the T-line region, so no T-line appears. Whether or not the sample contains virus, the latex-labeled rabbit IgG will react with the polyclonal goat anti-rabbit IgG antibodies on the control region (C) and a colored line will appear in the control region.
Once the assay is complete, the amount of latex ACE2 protein bound to the T-line is directly related to the concentration of novel coronavirus in the sample, whereas the amount of latex bound to the control region is not related to the concentration of coronavirus in the sample.
STORAGE AND STABILITY
The test is stable for 12 months if all components remain in the sealed pouch and the test is stored away from light at 2° Celsius.
