New data published Saturday night on Hadashot Sof Hashavua showed that rapid tests miss approximately half of COVID-19 diagnoses.

The Defense Ministry's Administration for the Development of Weapons and Technological Infrastructure took all of the antigen tests conducted this week by the various testing companies, and discovered that just 1.8% of those who underwent official antigen tests received a positive result - a rate far below that of the PCR tests.

The rate of those testing negative on antigen tests despite testing positive on PCR tests was 47%. At the same time, the percentage of those testing positive on antigen tests but negative on PCR tests was 37%
