The ICMR, thereafter, evaluated the kits of Guangzhou Wondfo Biotech and Zhuhai Livzon Diagnostics in field conditions and the results have shown wide variation in their sensitivity despite early promise of good performance for surveillance purposes.

The single page note issued by the ICMR said the RT-PCR throat/nasal swab test was the best use for diagnosis of COVID -19. It detected the virus early and was the best strategy to identify and isolate the individual, it added.
