A method for detecting Covid in exhaled air

2021-05-09T06:57:12.258Z

DECRYPTION - An expensive and large device can detect the chemical signature of the disease in the breath of infected people.



It is a painless, fast and precise technique for detecting Covid, which consists of simply blowing into an instrument as is done for a breathalyzer.

The difference is that the "tube" in which the air is exhaled must be connected to a mass spectrometer, an imposing and expensive machine capable of detecting minute traces of complex molecules (up to a few tens of molecules per quadrillion, i.e. 1 million billion billion!).

The idea is to identify and detect specific metabolites exhaled by people infected with Covid.

Funnyly, that's exactly what dogs trained to detect certain diseases do: their noses are unparalleled in their sensitivity to detecting tiny traces of volatile molecules.
