Dr Hilary explained: “It’s better to have 10,000 tests that are reliable and work than 25,000 tests and a third of them don’t work.
“We have to remember that testing is only valuable when the results are reliable.
“Other countries we know have had to send tests back because they weren’t reliable and that puts patients and staff in a dangerous position, so we have too few.
“We dramatically need to improve the number of tests being done.”
