BJP leader shoots himself dead in temple sanctum sanctorum

Bengaluru, Apr 28: Karnataka has found that the rapid antibody test kits for COVID-19 that the Centre supplied to the state have only 47% sensitivity. The state will be returning the kits to the Indian Council of Medical Research (ICMR).

Karnataka had received 11,400 rapid antibody test kits from the ICMR a few days back, out of which it had sent around 200 of them to NIMHANS for validation.

After the ICMR, on Monday, sent a circular to all states to return the test kits to the suppliers, Dr CN Manjunath, Director, Jayadeva Institute of Cardiovascular Sciences and Research, and nodal officer for lab testing in the state's COVID-19 task force, said, "We have cancelled the orders we placed to Guangzhou Wondfo Biotech and Zhuhai Livzon Diagnostics for one lakh rapid antibody test kits. Since the ICMR supplied us with 11,400 kits out of the 6.5 lakh kits it procured, we will be returning the kits to them."

Manjunath told said that the validation at NIMHANS revealed the kits to have only 47% sensitivity. Sensitivity is the ability of a test to identify the true-positives in a population, i.e., the actual number of people who've been infected with the disease. With the rapid antibody testing kits being shelved, the state's plan to randomly test high risk groups has taken a backseat. 

So far, the state has tested 43,791 samples. 

Karnataka now has 22 testing facilities -- 14 government and seven private labs. Many private labs have not tested any samples so far because of the lack of test kits (the state has made it clear that it will not provide test kits to private labs). So, getting an ICMR approval for testing has become a moot point.p

Agreeing to the setback the state's plans of ramping up testing has taken, Manjunath said, "It is true that RT-PCR test kits are in shortage. Even Pune's Mylabs had a shortage in supplying test kits. But we are relying on institutes like Kidwai, Narayana Health and Biocon's Syngene that have received approval for testing. They're big institutes and we hope that they will test a large number of samples."

On reports that the Centre has RT-PCR test kits that will last for only a week, he said, "We have test kits that will last for eight to 10 days. We have ordered for more. We are hoping to receive them before the current kits run out."

Bengaluru, May 24: Karnataka has conducted 2.03 lakh tests across the 57 Indian Council of Medical Research (ICMR) COVID-19 testing labs till Sunday morning, said the state Minister of Medical Education Dr K Sudhakar.

He informed that the state has doubled the number of tests in just 16 days after clocking 1 lakh tests on May 8.

"After clocking 1 lakh tests on May 8, we have doubled the number of tests in just 16 days. As on this morning, we conducted 2.03 lakh tests across our 57 ICMR COVID-19 testing labs. I congratulate doctors and lab technicians on this achievement," Sudhakar tweeted.

As many as 1,743 people have been detected positive for coronavirus in the state, of which 597 have been cured and discharged and 41 have succumbed to the infection, as per the Union Health Ministry. 

Bengaluru, Mar 30: The total number of COVID-19 cases in Karnataka has climbed to 88 on Sunday after five more persons tested positive for the lethal infection.

"Five more COVID-19 cases reported in Karnataka taking positive cases in the state to 88," said the State health department.

Of the five, one is a close contact of an earlier confirmed patient and the others are workers of a pharmaceutical company in Mysuru, from where a person had tested positive, the department said.

The country is under a 21-day lockdown to prevent the spread of coronavirus, which according to the Ministry of Health and Family Welfare, has infected 1,071 people so far.
