A NUMBER of faulty Covid swabs may have affected the accuracy and may have led to false positive results. Concerns have been raised over a ‘small number’ of of affected Covid-19 swabs which were used in hospital settings, health board-run community testing units and Welsh Ambulance Service Trust mobile testing units. Welsh Government confirmed they became aware of the issue on Friday 15. According to Public Health Wales, the swabs posed ‘little or no risk to public health’ but may have resulted in false positives. In a written statement earlier this week, Health Minister Vaughan Gething said: "As soon as this problem was discovered, all microbiology labs and testing centres in Wales were notified so that the affected swabs could be taken out of circulation.
