Coronavirus company news summary – Arizona researchers develop smartphone-based Covid-19 test – Seegene develops Covid-19 variant test

By Chloe Kent

University of Arizona researchers are currently working on a Covid-19 testing method that will utilise a smartphone microscope to analyse saliva samples and deliver results in approximately 10 minutes. Led by Jeong-Yeol Yoon, a biomedical engineering professor, the research will combine the speed of existing nasal swab antigen tests with the high accuracy of nasal swab PCR, or polymerase chain reaction tests.

OraSure Technologies has announced that its OMNIgene ORAL saliva collection kit, a product of its subsidiary DNA Genotek, was included in a US Food and Drug Administration (FDA) Emergency Use Authorization (EUA) granted to Ambry Genetics. The healthcare company will use the saliva collection kit in its Ambry Covid-19 RT-PCR saliva test to detect and identify the SARS CoV-2 RNA.

Seegene has developed the world’s first Covid-19 diagnostic test that can screen the SARS-CoV-2 virus to identify multiple mutant variations in a single reaction. The Allplex SARS-CoV-2 Variants I Assay test integrates at least ten of its proprietary technologies, including multiplex real-time PCR method of mTOCE™. This innovative technology allows the test to detect a target specific spot where mutation occurs, enabling precise detection and differentiation of the coronavirus as well as its mutated versions with a single tube of reagent.
