Washington, April 16: The Food and Drug Administration (FDA) authorised the first test, InspectIR Covid-19 Breathalyzer, to detect Covid-19 through the breath for emergency use.
FDA authorises first-ever breathing test for detecting Covid-19 infection
The InspectIR COVID-19 Breathalyzer uses a technique called gas chromatography gas mass-spectrometry (GC-MS) to separate and identify chemical mixtures and rapidly detect five Volatile Organic Compounds (VOCs) associated with SARS-CoV-2 infection in exhaled breath. When the InspectIR COVID-19 Breathalyzer detects the presence of VOC markers of SARS-CoV-2, a presumptive (unconfirmed) positive test result is returned and should be confirmed with a molecular test, the Food and Drug Administration (FDA) informed in a statement. The InspectIR Covid-19 Breathalyzer which is about the size of a carry-on piece of luggage is able to identify five volatile organic compounds tied to the coronavirus in a person's breath using a technique known as gas chromatography gas mass-spectrometry, delivering results within three minutes, according to the FDA, the statement reads.

The FDA also noted that the InspectIR COVID-19 Breathalyzer had a 91.2 per cent sensitivity rate, which measures the per cent of correctly identified positive test samples. However, the health agency said that a molecular test should be used to confirm positive test results returned by the COVID-19 breath test. Jeff Shuren, director of the FDA's Center for Devices and Radiological Health, in a statement, said, "Today's authorization is yet another example of the rapid innovation occurring with diagnostic tests for COVID-19," as per The Hill. Nearly 100 of the InspectIR COVID-19 Breathalyzers, each of which the FDA said can be used to test roughly 160 samples per day, are anticipated to be made each week.
