Mr Swinney says people who have taken a coronavirus test should receive the results within 24 hours.
"We have to make sure that is delivered on a sustained basis in all parts of the country and in all laboratories," he says.
That is a critical priority, he adds, to help make sure that contact tracing is able to be deployed swiftly.
