There had been a backlog of results built up over the Christmas period but Public Health Scotland said today it is “continuing to see improvements in turnaround times, and are continuing to monitor the situation”.
It added: “There continues to be large volumes of tests being processed by labs; this and the festive period have impacted turnaround times resulting in delays between specimens being taken and results being received and reported.”
