Press Release:- Whole genome sequencing (WGS) testing to detect COVID-19 (SARS-CoV-2) variants will be underway at the CARPHA Medical Microbiology Laboratory (CMML) from Monday, 15 November 2021. The process will allow CMML to monitor COVID-19 and track specific mutations of COVID-19 that have been circulating in CARPHA Member States. This new service will provide a turnaround time of 14 days after receipt of samples by CMML from Member States. Each virus has its own genomic sequence, characterised by a unique “fingerprint”. Whole genome sequencing (WGS) is the most comprehensive method for genetic disease testing and can detect nearly all types of
