For the past two days — Wednesday and Thursday — the number of tests in the city has been crossing the 15,000 mark. Of these, around 7,000 were antigen tests. Testing of the BMC's own frontline workers has also increased the total. The positivity rate of the antigen tests, however, remains less than one-third of the RT-PCR tests and needs better follow-up in case of negative results.

On Wednesday and Thursday, the number of RT-PCR tests was 8,400, antigen tests increased to 7,300 and 6,700 respectively, with their share increasing from 25 per cent to nearly 50 per cent.
