Bengaluru,  Karnataka health department has devised a random Covid testing strategy using RT-PCR pooled sample technique to examine people who generally come in contact with a large number of people, an official said on Wednesday.

"Those who are likely to come in contact with maximum number of persons in markets, malls etc should be included in the samples as per the capacity of the districts which should be inclusive of samples collected by routine testing," said Additional Chief Secretary Jawaid Akhtar.
