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...

NIST Scientists Enhance Frequency Comb Breathalyzer Enabling It to Detect Multiple Disease Biomarkers

Device could pave the way for real-time, noninvasive breath analysis to detect and monitor diseases and be a new service medical laboratories can offer Breathalyzer technology is not new, but until now human breath detection devices have not been comparable to clinical laboratory blood testing for disease detection and monitoring. That may soon change and there are implications for clinical laboratories, partly because breath samples are considered to be non-invasive for patients. Scientists...

Will Blowing in a Device Be Useful in Screening for COVID-19? FDA Grants Its First EUA for a Breathalyzer SARS-CoV-2 Screening Test

InspectIR COVID-19 Breathalyzer identifies a chemical signature associated with SARS-CoV-2 in about three minutes with 91.2% sensitivity and 99.3% specificity One company is hoping that it can make breathalyzers a viable, easier way to screen for SARS-CoV-2. It will soon have the opportunity to learn if consumers will accept this form of screening for COVID-19, as its device recently obtained an Emergency Use Authorization from the FDA. On April 14, 2022, InspectIR Systems, LLC, of Frisco,...

FDA Expands Approval of Gastric Emptying Breath Test for Gastroparesis to Include At-home Administration Under Virtual Supervision

It may not be a boom trend, but more non-invasive diagnostic tests are coming to market as clinical laboratory tests that use breath as the specimen Here’s a development that reinforces two important trends in diagnostics: non-invasive clinical laboratory assays and patient-self testing. Recently, the FDA expanded the clearance of one diagnostic test to allow patients to collect their own breath specimen at home under the supervision of the test manufacturer’s telehealth team. The C-Spirulina...

NASA Develops the ‘E-Nose,’ a Handheld Breath Analyzer That Can Measure Multiple Biomarkers Used in Medical Laboratory Tests

Noninvasive diagnostic technology developed for space travelers and warfighters might eventually be used by clinical laboratories and physician office labs To solve the problem of how to perform clinical laboratory tests on astronauts living for months at a time in the International Space Station (ISS), researchers associated with the National Aeronautics and Space Administration (NASA) are developing diagnostic tests that use human breath as the specimen. Last month, the research team...
