Advice follows discovery of anomalies in which people had positive lateral flow tests but negative lab results
People should self-isolate if they have Covid-19 symptoms even if they have a negative PCR test result, according to a regional public health official, after a number of cases where people tested positive using lateral flow tests – but then negative with PCR.
Anomalies have been reported by people in south-west England over the past week, with one public health official saying they were aware of a “high number” of inconsistent test results, according to reports by the i newspaper.
