As more and more variants are emerging, CTK’s commitment to ensure that CTK’s OnSite® COVID-19 Ag Rapid Test isn’t affected by these mutations is ongoing. We analyzed the NP mutations present in the California, Nigeria, and India/Delta variants and mapped them on the SARS-CoV-2 NP protein recognized by CTK’s OnSite® COVID-19 Ag Rapid Test using ELISA and peptide scanning. We found that.... Read Full Article >
Rapid identification and isolation of COVID-19 patients by prescreening VTM samples? The OnSite COVID-19 Ag Rapid Test by CTK might be the answer!
The performance of the OnSite® COVID-19 Ag Rapid Test by CTK was evaluated using sample material from nasopharyngeal swabs stored in viral transport media. The swabs were previously used to screen for SARS-CoV-2 using qPCR. The OnSite® COVID-19 Ag Rapid Test sensitivity was between 86-90% depending on the viral load*. The study used leftover sample material selected from samples sent.... Read Full Article >
