Tata Medical and Diagnostics, the healthcare unit of India's Tata Group, launched its Covid-19 test kit which will be made available at laboratories and hospitals from December, its CEO Girish Krishnamurthy told Reuters.

The government-approved test, which can provide the final result within 90 minutes, will be manufactured at Tata's plant in Chennai in southern India which has the capacity to produce 1 million test kits a month, Krishnamurthy said.

The launch comes as India's Covid-19 cases rose by 45,903 to 8.55 million with deaths rising by 490 to 126,611, government data showed.
