Airport bomb: Home minister refuses to call Aditya Rao a terrorist, accuses Opposition of appeasing minorities

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, Apr 1: As many as 12 of the 40 identified people from Karnataka, who attended Tablighi congregation in Nizamuddin, Delhi, have tested negative for COVID-19, state Health Minister B Sriramulu said in a tweet on Wednesday.

It is also learnt that 62 foreigners from Indonesia and Malaysia, who attended the congregation, have visited the State and 12 of them have been quarantined, the tweet said.

''The health department, in association with the Home department, has jointly started the process of identifying all the 300 who attended the event,'' he said.

Bengaluru, Apr 18: The Karnataka government has fixed the cost of test for COVID-19 in private laboratories at Rs 2,250, an official said on Friday.

"Based on the discussions and negotiations, the cost per test has been fixed at Rs 2,250. This includes the screening test and a confirmatory test," said order by Health and Family Welfare Department's Additional Chief Secretary Jawaid Akhtar.

A total of 16 laboratories (11 government and 5 private) have been approved by the Indian Council of Medical Research (ICMR) for testing samples of possible COVID-19 cases in the state.

Realising that early detection of coronavirus cases and timely treatment was the need of the hour, meetings were held to rope in more private laboratories to conduct COVID-19 sample tests.

As per the protocol by the Centre, testing the samples of suspected COVID-19 cases can be taken up in private laboratories subject to conditions which include sharing the lab data pertaining to the diagnosis of COV1D-19 with the state government and with the ICMR on a timely basis.

As per the Union Health Ministry, 353 people have infected from coronavirus in the state of which 83 are cured and discharged and 13 succumbed to the virus.
