Lateral flow tests that can detect Strep A in just five minutes are available on the NHS in Wales but not England due to a lack of funding, it is reported.
The £7.50 tests can help to fight the infection that has now seen 15 children die in the UK by tackling cases quickly while ensuring that antibiotics go to only those who need them.
And they could also help to reduce the demand on GPs with patients unsure of whether they have Strep A or not.
