And Anna Schuh, professor of molecular diagnostics at the University of Oxford, warned that the test gets it wrong when it calls a positive result "almost half of the time", which she said was "disappointing as it is only fractionally better compared to tossing a coin".

Better consult with statisticians before making a policy to use those tests. Depending on the rate of false positives, doing more tests doesn't necessarily improve public health. If this lead to too many unnecessary procedures and unnecessary follow up tests, it may divert resources aways from people who actually need treatment.
