Breath Sample Is Used by Opteev Technologies’ Combined COVID/Influenza/RSV Screening Device with 95% Sensitivity and 90% Specificity

Clinical laboratories and point-of-care settings may have a new diagnostic test if this novel handheld device and related technology is validated by clinical trials Efforts to develop breath analyzers that accurately identify viral infections, such as SARS-CoV-2 and Influenza, have been ongoing for years. The latest example is ViraWarn from Opteev Technologies in Baltimore, Maryland, and its success could lead to more follow-up PCR tests performed at clinical laboratories. ViraWarn is a...

Diagnosing Ovarian Cancer Using Perception-based Nanosensors and Machine Learning

Two studies show the accuracy of perception-based systems in detecting disease biomarkers without needing molecular recognition elements, such as antibodies Researchers from multiple academic and research institutions have collaborated to develop a non-conventional machine learning-based technology for identifying and measuring biomarkers to detect ovarian cancer without the need for molecular identification elements, such as antibodies. Traditional clinical laboratory methods for detecting...

German Researchers Create Non-invasive Lab-on-a-Chip Biosensor That Detects Antibiotic Levels from Breath Samples

Should the device prove effective, it could replace invasive point-of-care blood draws for clinical laboratory testing during patient drug therapy monitoring What if it were possible to perform therapeutic drug monitoring (TDM) without invasive blood draws using breath alone? Patients fighting infections in hospitals certainly would benefit. Traditional TDM can be a painful process for patients, one that also brings risk of bloodline infections. Nevertheless, regular blood draws have been the...

FDA’s New Next-Generation DNA Sequencing Platform Intended to Increase Collaboration among Scientists, Pathologists, and Clinical Laboratory Experts

Federal agency hopes its open-source precisionFDA web portal will aid in development of laboratory-developed tests and inform regulatory decision-making One recent initiative launched by the Food and Drug Administration (FDA) to foster the greater sharing of genetic information may be of some value to pathologists and clinical laboratory scientists  who are developing laboratory-developed tests (LDTs) that incorporate molecular and genetic technologies. The FDA unveiled an open-source platform...
