Rapid tests must be molecular and operated by specialised technicians, warned the doctor and professor of Microbiology at the University of Lisbon (UL), Thomas Hanscheid. “Some companies can miniaturise molecular tests done in labs, but the tests with quality are expensive”, said the professor, according to Lusa.

Rapid tests for infectious diseases were developed in the 1980s due to malaria, in a format similar to a pregnancy test, but what is now required for covid-19 is different, the professor warned.
