Dr Clare Craig explains COVID-19 testing in light of the mass testing currently being carried out in Liverpool. Dr Craig highlights the difference between the PCR test used previously and the Rapid Test which is being used by the army for testing in Liverpool. The PCR test used for COVID-19 testing Dr Clare Craig explains, was not designed as a diagnostic test, as stated on the box containing the test. Yet it’s use has led to lockdowns and possibly unnecessary hospital admissions. Dr. Craig suggests it would be expedient to retest all those who have been admitted to hospital supposedly with COVID-19 with the Rapid Test to establish whether those are real cases of Coronavirus and whether there is a resurgence of infections. She suspects, by retesting, we will see far fewer cases of the virus than expected.
