Washington, December 12: A study in the Journal of Medical Internet Research introduced Biocogniv's new AI-COVID software that can easily predict the probability of COVID-19 infection.

A team of researchers from the University of Vermont and Cedars-Sinai discovered high accuracy in predicting the probability of COVID-19 infection using routine blood tests, which can help hospitals reduce the number of patients referred for scarce PCR testing. Also Read | Christmas 2020 Kids Costume Ideas: 5 Different Ways to Dress Your Children for the Festive Season (Watch Videos).

Lead author and University of Vermont Assistant Professor Timothy Plante, M.D., M.H.S said , "Nine months into this pandemic, we now have a better understanding of how to care for patients with COVID-19, but there's still a big bottleneck in COVID-19 diagnosis with PCR testing."

PCR testing is the current standard diagnostic for COVID-19, and requires specific sampling, like a nasal swab, and specialized laboratory equipment to run.

"According to data from over 100 US hospitals, the national average turnaround time for COVID-19 tests ordered in emergency rooms is above 24 hours, far from the targeted one-hour turnaround," Biocogniv Chief Operating Officer Tanya Kanigan, Ph.D., said. Complete Blood Count and Complete Metabolic Panels are common laboratory tests ordered by emergency departments and have a rapid turnaround time. These tests provide insight into the immune system, electrolytes, kidney, and liver.

The researchers were able to train a model that analyzes changes in these routine tests and assigns a probability of the patient being COVID-19 negative with high accuracy.

Jennifer Joe, M.D., an emergency physician in Boston, Mass. and Biocogniv's Chief Medical Officer told, "AI-COVID takes seconds to generate its informative result once these blood tests return, which can then be incorporated by the laboratory into its own test interpretation."

Cedars-Sinai pulmonary and internal medicine specialist Victor Tapson, M.D., says such assistive tools that help physicians rule out possible diagnoses are familiar in emergency medicine.

"For example, a low D-dimer blood test can help us rule out clots in certain patients, allowing providers to skip expensive, often time-consuming diagnostics such as chest CT scans," said Tapson. The Biocogniv team believes a secondary benefit of laboratories incorporating AI-COVID might be reduced time for traditional PCR results.

"With the help of AI-COVID, laboratories might relieve some of the testing bottlenecks by helping providers better allocate rapid PCR testing for patients who really need it," said Joe.

The AI-COVID model was validated on real-world data from Cedars-Sinai as well as on data from geographically and demographically diverse patient encounters from 22 U.S. hospitals, achieving an area under the curve (or AUC) of 0.91 out of 1.00.

Biocogniv Chief Scientific Officer George Hauser, MD, a pathologist said, "This enables the model to achieve a high sensitivity of 95 per cent while maintaining moderate specificity of 49 per cent, which is very similar to the performance of other commonly used rule-out tests." Also Read | Toys, Handicrafts Made by Local Artisans Exempted From Quality Control Order, Announces Piyush Goyal.

"I'm honoured to have such an impressive team of medical scientists from the University of Vermont and Cedars-Sinai as collaborators invalidating this timely model," Biocogniv CEO Artur Adib, PhD, said.

"AI has progressed considerably; the time is now to leverage this powerful tool for new healthcare breakthroughs, and we're glad to direct it to help hospital laboratories and providers combat the current COVID-19 crisis," added Adib.
