Geneva - The International Air Transport Association (IATA) urged governments to accept best-in-class rapid antigen tests in fulfillment of COVID -19 testing requirements following the publication of new research by OXERA and Edge Health.The OXERA-Edge Health report (pdf) commissioned by IATA, found that antigen tests are: • Accurate: the best antigen tests provide broadly comparable results to PCR tests in accurately identifying infected travelers. The BinaxNOW antigen test, for example, misses just one positive case in 1000 travellers (based on an infection rate of 1% among travelers). And it has similarly comparable performance to PCR tests in levels of false negatives. • Convenient: processing times for antigen tests are 100 times faster than for PCR testing • Cost-efficient: antigen tests are, on average, 60% cheaper than PCR tests.
