Covid clinical symptoms, CT scans/X-rays should be used to rule out false negatives: Experts

India's top experts on Monday said RT-PCR tests detect coronavirus in around 80 per cent of the cases, so clinical features and CT scans/chest X-rays should be used to rule out false negatives in symptomatic patients followed by a repeat test after 24 hours.

Amid SARS COV-2 ''variants of concern'' circulating, they said RT-PCR tests do not miss mutations as the ones being used in India target more than two genes.
