Unfortunately, both immune- and molecular-based methods, including enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR), require prior knowledge of the strains. Another technique known as deep sequencing is another promising new approach, but obtaining sufficient viral reads for it to work well depends on the quality of the sample and its preparation. Processing steps involve incorporating different benchtop equipment, reagents, and technical expertise. … [Read more...] about I’m a scientist. We should try testing for COVID-19 using laser beams
