Cartridge lab tests can be performed on cartridges smaller than a cell phone and require a lab.
The study, led by scientists at Imperial College London and published in “The Lancet Microbe” this week, referred to high speed in 386 National Health Service (NHS) employees and patients and had a sensitivity of more than 94% and 100%. . Specificity.
“These effects recommend that the test, which can be performed next to a patient’s bedside without the desire to take care of any samples, has accuracy comparable to popular laboratory tests,” said Professor Graham Cooke, study director at the Department of Infectious Diseases at Imperial College London.
“Many checks involve a compromise between speed and accuracy, but this check achieves both. Developing an effective bedside check in less than 3 months has been a collaboration between groups of engineers, doctors and virologists,” he said.
It is being used effectively in 8 hospitals in London lately and is expected to be implemented nationally in the UK as knowledge of the device continues to be collected for ongoing evaluation.
Imperial College London said the UK government had recently placed an order for 5. 8 million kits.
To perform the test, a patient’s pediatric-sized nasal pad is inserted into the device, which then looks for genetic lines belonging to SARS-CoV-2 or the new coronavirus, which causes the infection.
You get a result in 90 minutes, compared to traditional COVID-19 verification that provides a result in 24 hours.
According to the study team, verification is developing lately to evaluate influenza A, influenza B and RSV, as well as COVID-19.
The device, produced through London-based pop-up DnaNudge, was used in 280 NHS staff members with suspected COVID-19, 15 patients in case of injury and emergencies (A
The percentage of those who tested positive for COVID-19 screened at the height of the pandemic was 18%.
Effects showed that 67 samples tested positive for CovidNudge, compared to 71 positive effects against a popular range of NHS laboratory devices, representing the price of 94% sensitivity.
”DnaNudge verification was developed as a service for on-site and non-laboratory visitors that can be provided on a giant scale, so it obviously provides a very significant perspective in terms of massive population verification during the Covid-19” pandemic,’ said Regius Professor Chris Toumazou, CEO and co-founder of DnaNudge and founder of the Institute of Biomedical Engineering at Imperial College London.
“The platform is suitable for testing network and number one services with the possibility of use in non-health environments, such as nursing homes, schools, transportation centers, offices and, to bring the arts back to theaters and venues. Additional studies on actual efficacy in non-clinical settings would be needed prior to widespread deployment,” he said.
The team, which included imperial scientists and physicians and several NHS hospital trusts, assessed sensitivity and specificity.
Sensitivity is a measure of the extent to which a check provides a positive outcome for others with the disease and is an indication of the likelihood of a check producing false negative results.
Specificity, on the other hand, is a measure of a check’s ability to give a negative result to a user who has the disease and is an indication of the likelihood of false positives.
“As an organization, we focus on employing studies and innovation to continuously improve attention. Getting precise effects for doctors and their patients as temporarily as you can imagine makes a big difference in the way we handle clinics safely and are very impatient. To implement it more broadly,” said Dr. Bob Klaber, Director of Strategy, Research and Innovation at Imperial College Healthcare NHS Trust.
The device has been approved through the UK Health and Medicines Regulatory Agency and has also been given the CE mark, allowing for further use in non-clinical locations. The team explains that the device is Wi-Fi enabled. Fi, which allows the verification result to be sent securely to a hospital’s recording system.
The tests were conducted between April 10 and May 12 at 3 NHS sites: St Mary’s Hospital, Imperial College Healthcare NHS Trust, London; Chelsea
It was supported through the National Institute of Health Research, Imperial Biomedical Research Center.
