Smartphone-based COVID-19 detection test from Australia shows high accuracy

ASX-listed digital well being agency ResApp Health has introduced that its pilot medical trial for a smartphone-based COVID-19 screening test has achieved optimistic outcomes.

The new diagnostic app, which makes use of machine studying to research the sound of a affected person’s cough, was reported to appropriately detect COVID-19 in 92% of individuals with the an infection through the trial. With a 92% sensitivity, it exceeds real-world measured sensitivity of fast antigen assessments, ResApp claims.


The medical trial within the United States and India concerned 741 sufferers with round 60% of them COVID-19 optimistic.

Based on preliminary outcomes, the app was additionally discovered to be “outstanding,” having reached an space beneath the curve of 0.9, when measured for the way properly it distinguishes between two diagnostic teams. It additionally obtained 80% specificity in figuring out sufferers who examined damaging for COVID-19.

To be certain that its algorithms are detecting COVID-19, it was checked towards the Breathe Easy dataset, which incorporates information from over 1,000 sufferers with varied non-COVID-19 respiratory situations.

ResApp additionally shared that the app confirmed “consistent performance” over two intervals, one when Delta was the key variant and the opposite when Omicron was the dominant variant.

The firm additional famous that the app demonstrated “lower” efficiency in asymptomatic sufferers, though it solely recruited a small variety of them.

ResApp stated it is going to publish the outcomes of its medical trial in a peer-reviewed journal “in the coming weeks”.


The World Health Organization has warned that the worldwide pandemic is way from over and that well being techniques should be ready to face extra harmful variants.

ResApp goals to initially deliver its newest screening answer in locations the place frequent COVID-19 testing is required, comparable to workplaces, hospitals, faculties, journey areas, sports activities venues, leisure hubs, and aged care centres. With its smartphone-based test, fast antigen or PCR assessments can be required much less to substantiate COVID-19 in these settings given its high sensitivity and specificity.

ResApp CEO Tony Keating stated they’re now reaching out to regulators throughout markets and have already engaged with world well being tech firms to roll out its app-based screening test.

Moreover, the COVID-19 screening app additionally has the power to “improve security and reporting of results” utilizing biometric identification like facial recognition.


Other tech builders have constructed algorithms to detect COVID-19 by analyzing sufferers’ cough sounds. In 2020, researchers from the Massachusetts Institute of Technology within the US developed an AI instrument to diagnose COVID-19 that was skilled utilizing over 70,000 audio recordings, together with these from contaminated sufferers. In October final yr, Andhra Medical College in India tried out Salcit Technologies’ Swaasa AI platform, which conducts an audiometric evaluation of cough sounds, together with temperature, oxygen saturation, signs, of suspected COVID-19 sufferers.

Meanwhile, Breathonix, a spin-off firm from the National University of Singapore, has developed a breath test that may quickly detect COVID-19 inside a minute.


“By rapidly ruling out COVID-19, ResApps COVID-19 test would significantly reduce the number of rapid antigen and PCR tests required, while still maintaining the disease surveillance needed to manage the continued impact of COVID-19. The simplicity, ease of use and unlimited scalability of ResApps test will be welcomed by public health officials around the world,” Catherine Bennett, a professor and the chair of Epidemiology at Deakin University, commented.
