In a bid to strengthen the COVID-19 testing capacity, the ICMR is going to operationalise two rapid testing laboratories and 49 additional testing centres by the end of this week.
A rapid testing laboratory will be equipped to test as many as 1,400 samples each day. These high throughput systems will be set up one each in Delhi-NCR and Bhubaneswar to exponentially increasing rapid diagnosing of COVID-19.
The additional 49 testing centres will be at various medical colleges and other places. It includes the Council of Scientific and Industrial Research (CSIR), Department of Biotechnology (DBT), and Defence Research and Development Organisation (DRDO).
