Once machine learning identified a potential COVID-19 signature, the team tested the accuracy of the device on a subset of participants. In the test set, the device showed 76% accuracy in distinguishing COVID-19 cases from controls and 95% accuracy in discriminating COVID-19 cases from lung infections. The sensor could also distinguish, with 88% accuracy, between sick and recovered COVID-19 patients. Although the test needs to be validated in more patients, it could be useful for screening large populations to determine which individuals need further testing, the researchers say. ..." – (Og "Multiplexed Nanomaterial-Based Sensor Array for Detection of COVID-19 in Exhaled Breath" https://pubs.acs.org/doi/10.1021/acsnano.0c05657 ) </ref> at bestemme tilstedeværelsen af [[coronavirus]] i udåndingsluften.
Fra første halvdel af 2020 blev idéen om en praktisk test af coronavirus – [[COVID-19]] – på grundlag af udåndingsluften udviklet samtidigt af ikke-relaterede forskningsgrupper i USA, Holland, Finland, Israel, England, Australien og Tyskland.<ref>Staff, [https://www.hospimedica.com/covid-19/articles/294781828/coronavirus-detecting-breathing-device-could-potentially-give-a-diagnosis-in-less-than-one-minute.html "Coronavirus-Detecting Breathing Device Could Potentially Give a Diagnosis in Less than One Minute"], HospiMedica International, 20. april 2020.</ref><ref>Anon, [https://eurekalert.org/pub_releases/2020-04/aabu-nct041620.php "New coronavirus test that is eight times faster can help locate asymptomatic carriers"] hos Eurekalert.org, 20. april 2020 – "EurekAlert!" hører under AAAS, ''American Association for the Advancement of Science'', [[:en:American Association for the Advancement of Science#EurekAlert!|(en)]]</ref>
