An Alcohol Meter to Detect Covid-19? On Scientists.


A few other studies They also detected unique chemical patterns It’s on the breath of Covid-19 patients, and some devices are claiming impressive results. In a study A team of Dutch researchers from SpiroNose, which included 4,510 participants, reported that the device accurately identified at least 98 percent of infected people, even in a group of asymptomatic participants. (The study, which includes researchers from Breathomix, has not yet been peer-reviewed.)

However, the study found that SpiroNose has a relatively high false-positive rate. Due to this problem, the device does not provide consumers with a definitive diagnosis; results are either negative or inconclusive, in which case a standard PCR test is performed.

Ms de Vries said that dozens of test sites in the Netherlands are currently using the machine, but there are some glitches. in May, Science reported Amsterdam’s public health authorities suspended the use of SpiroNose after 25 false negatives. Authorities later determined that user error was largely responsible, and Ms de Vries said that SpiroNose scanning has resumed.

Other groups are working on their own alcohol meters. Researchers at the Children’s Hospital of Philadelphia, defined A breath trace of COVID in children is now trying to identify breath markers known as a rare but dangerous complication of the disease. multisystem inflammatory syndrome (MIS-C) in children.

At the Children’s Hospital of Philadelphia, who conducted the research, infectious disease specialist Dr. “Clinicians on the front are really struggling with which children we should be most concerned about,” said Audrey Odom John.

Dr. In addition to examining the VOCs emitted by Covid patients, Davis and colleagues are analyzing what is known as exhaled breath condensation, which is a concentrated solution of tiny liquid droplets or aerosols found in the breath. These aerosols contain all kinds of complex biological molecules, including proteins, peptides, antibodies and inflammatory markers.
