CTK’s Aridia Real-Time COVID-19 PCR Tests detect new SARS-CoV-2 variants, including U.K., South Africa, Brazil, California, Nigeria, and India/Delta variants

CTK’s goal during the current COVID-19 pandemic is to provide quality diagnostic tools for the detection of SARS-CoV-2, such as the Aridia Real-Time COVID-19 PCR Test. As new SARS-CoV-2 variants are identified, CTK has been working on confirmation studies to ensure that the performance of the Aridia COVID-19 Real-Time PCR Test isn’t affected by these mutations. The Aridia COVID-19 Real-Time.... Read Full Article >

UPDATE: OnSite Covid-19 Ag Rapid Tests detect new SARS-CoV-2 variants – California, Nigeria, and India/Delta variants

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 >

CTK’s OnSite Covid-19 Ag Rapid Tests detect newly identified U.K., South Africa, and Brazil SARS-CoV-2 variants

In December 2020, CTK shared that we had no reason to believe that the U.K. variant would affect the OnSite COVID-19 Ag Rapid Test’s performance, and we would work on confirmation studies.  Since then, multiple SARS-CoV-2 variants have been circulating globally, which led us to include them in our confirmation studies. The OnSite COVID-19 Ag Rapid Test detects the presence.... Read Full Article >

Ongoing studies indicate that CTK’s OnSite Covid-19 IgG/IgM Rapid Tests detect antibodies in response to COVID-19 vaccines

CTK’s OnSite COVID-19 IgG/IgM Rapid Test’s performance in detecting antibody responses following COVID-19 vaccination was evaluated in a cohort of 20 subjects that had no detectable levels of anti-SARS-CoV-2 antibodies before vaccination. All 20 subjects (100%) had their first positive result on the OnSite COVID-19 IgG/IgM Rapid Test 9 to 16 days post-vaccination, showing this test’s high sensitivity. Our ongoing....
