Bitscopic's Machine Learning Algorithm Detects COVID-19 from Standard Blood Labs

Press Release | Bitscopic | October 2, 2020

October 2, 2020 -- Palo Alto, California - (PR Distribution™) - Bitscopic Inc., a Silicon Valley based healthcare analytics company, announced today they have developed a machine learning prediction model that can identify COVID-19 infected patients using data from standard laboratory blood tests. The model, published in "Clinical Infectious Diseases," was developed using laboratory data from over 75,000 COVID-19 infected Veteran patients receiving care at VA medical centers.

Payam Etminani, Bitscopic's CEO, said: "We are very excited by these results, as it demonstrates that inexpensive and easily attainable patient data can be used to construct a diagnostic fingerprint that can identify symptomatic cases of COVID-19. We are learning how the relatively blunt instrument of routine blood tests, through the power of machine learning, can be crafted into something approaching a precision tool."

Payam EtminaniDescribing the development of the algorithm, Etminani said: "Our team reviewed some early published scientific articles on COVID-19 and noticed that patients had abnormal blood test values, particularly decreased white blood cell counts and increased C-reactive protein. As we have been partnering with the U.S. Department of Veterans Affairs Public Health Surveillance and Research program office (PHSR) for almost a decade now, we had access to a sizable amount of high-quality normalized clinical data through our Praedico™ platform. Using this data, we found that 20 standard blood tests carried enough information to predict a COVID-19 infection with a specificity of 87% and a sensitivity of 82%."

The model was also successful in detecting false negatives that had not yet shown in PCR tests. When multiple negative COVID-19 molecular test results were obtained from the same patient over a period of a few days, followed by a positive result, the model identified the initially negative results as consistent with COVID-19 infection two-thirds of the time. This suggests that the prediction model might be used as a fully independent complement to molecular testing and help pinpoint false negatives.

The Bitscopic COVID-19 detection algorithm will soon be available for hospitals as a dashboard and will also be included in Bitscopic's PraediAlert product which is used to monitor and prevent Hospital Acquired Infections (HAIs). Beyond COVID-19, the Bitscopic team is exploring how similar machine learning methods can detect other medical conditions from easily available biomarkers.
