How can you get to know to isolate if you are not displaying any symptoms of COVID-19? With a rise in asymptomatic cases, bulk testing for COVID-19 is a good potential measure to control the pandemic's spread as it is about identifying those who may have a virus but being asymptomatic may not know it yet and maybe passing it on silently. Instead of being used as a diagnostic tool, the rapid tests allowing bulk testing is a form of a proactive measure aimed at preventing the outbreaks. Organizations can thus keep new case numbers low at their workplaces by conducting a bulk screening of the employees. Moreover, with a very low turnaround time of the antigen tests, bulk testing saves time and enables the organizations to get the maximum number of results within the same day.
Saliva-based tests and antigen tests can be done for bulk testing as these tests return results within a short time ranging from few minutes to few hours, depending on the test. Another test that allows mass testing is a lateral flow test, which is easy, cheap, and very fast. Like a pregnancy test, this one-piece kit of the lateral flow test marks a positive test when fluid from a nasal swab or saliva is applied on one end. It eliminates the need for laboratories, thus saving time and money.
Bulk testing typically requires screening people in a shared space at least once a week, whether or not they have symptoms. Keeping in mind the resistance towards wearing masks, it would not be easy to get full support from the employees for frequent testing. However, the organizations can attach some incentives with the screening to motivate employees for active participation in the mass testing.
