Paving way for the return of stranded Mangalureans from Gulf is your responsibility: U T Khader tells DK MP

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."

Kasaragod, Mar 11: An accused in a POCSO case here has been put in an isolation ward at the Government hospital on Wednesday as he was suspected having symptoms of Covid19.

The accused has been absconding ever since a case under POCSO Act was registered against him a year ago.

However acting on a tip off, the Kasaragod police arrested him at Mangalore Airport recently and was produced before the Court and was remanded to judicial custody.

Karwar, June 29: The additional sessions court, Sirsi town police station and office of the deputy superintendent of police in Uttara Kannada district were sealed on Sunday after an undertrial was found positive for Covid-19.

The undertrial, accused of stealing a bike, from Hubballi was arrested by Sirsi police and had initially tested negative. He was confirmed infected when his samples were tested the second time.

He was arrested by Dharwad police in connection with a bike theft case. During interrogation it was found that he had stolen bikes in Sirsi too. Sirsi police had brought him from Dharwad sub-jail for the interrogation and was produced in the court.

The accused was in Manipal jail for some time after he was convicted there for the bike theft. While bringing him to Sirsi the police had wore PPE kits.

When he was produced in the court the judge had reportedly directed the police test him for covid as he had some symptoms.

His swab was collected and sent to the lab. In the first test the result was negative but it was positive in another test. At that time he was in Sirsi sub-jail. 10 police officials who had come into his contact have been quarantined. The police station has been sealed down and the court will be closed down on Monday and Tuesday.

All the under trails who were kept with him in the sub-jail have been isolated and their swab has been sent for the testing.
