Researchers from the University of Edinburgh have launched a Covid-19 test called the TestEd to detect the SARS-CoV-2 infection from a saliva sample deposited in a tube. The researchers have applied an innovative approach called hypercube sample pooling where a large number of samples can be processed at once. The Medical Research Council (MRC) recently awarded TestEd a $2.50m grant to scale up its testing of students and staff to reaffirm its efficacy.
