The first proposal is retest people for genomics within 24 hours of every positive case. The problem we're trying to solve here is that only 50 percent of samples have been genomically sequenced. Genomic testing is clearly important for identifying linkages and the heritage of the virus, but we've only been able to sequence 50 percent. As the Minister said to me in written question 15645, the methodology used in some diagnostic laboratories means there is sometimes no residual sample to be sent to the Institute of Environmental Science and Research. Furthermore, often samples are taken for the specific purpose of a positive or a negative coronavirus swab test, but a different technique of sampling and processing may be required for genomic sequencing. I'm proposing that every positive test be resampled within 24 hours for the purposes of genomic sequencing.
