Researchers developed a COVID-19 testing method that uses a smartphone microscope to analyze saliva samples and deliver results in about 10 minutes. The method combines the speed of existing nasal swab antigen tests with the high accuracy of nasal swab PCR (polymerase chain reaction) tests. They are adapting an inexpensive method that they originally created to detect norovirus — the microbe famous for spreading on cruise ships — using a smartphone microscope. They plan to use the method in conjunction with a previously developed saline swish-gargle test.
