The Test to Release Covid-19 test must be a PCR swab.
PCR Testing is the most sensitive test that is currently available, able to detect active infection some days before the patient is infectious or symptomatic. It is the gold standard test; used in the NHS daily.
The test offered by SYNLAB will be COVID-19 PCR Swab Test (PCR-RNA SARS-CoV-2) to provide peace of mind to customers as part of the new Test to Release scheme available from 15th December 2020 to all passengers returning to England wishing to reduce the quarantine period.
PCR testing is performed in machines that cycle through different temperatures. As the process of changing temperature takes some time, the process is longer than other processes.
