This isn’t quite right. Although there are no direct Delta variant tests, PCR tests that are positive for SARS-CoV-2 can undergo genetic analysis such as ‘genomic sequencing’ which tells us if it is the Delta (or another) variant. This means it is possible to accurately identify if someone is unwell with the Delta variant of Covid-19.
