New RNA-Based Breath Test Can Detect Covid-19 Particles In Seconds
Using breath to detect Covid-19? Yep, scientists have found a way to do that!?In a new study published in The Journal of Molecular Diagnostics, scientists outlined their new tech called "The Bubbler."
"It relies on viral DNA detection to diagnose SARS-CoV-2," MedicalXpress reported. Designed like a breathalyser, the Bubbler gets its name from the bubbling sound that takes place whenever a patient exhales into the device.
More than a regular test
Besides reverse-transcribing RNA from airborne Covid-19 particles into DNA that may be tested via PCR, the Bubbler can also barcode that DNA.
This means that samples can be linked directly to the patient they have come from and be directly used for sequencing. There's more! The novel tech can also provide additional information like viral load within a sample and the strain behind the infection.

With no need to stabilise a sample, the test can be performed even in home settings.
In many ways, the Bubbler functions similarly to PCR tests that are used in hospitals. It builds on that tech to improve readings, for it can detect airborne viral particles - offering a better look at potential contagion.
Suitable for many spaces
According to the brains behind the Bubbler, the device can be tweaked to function in an array of public spaces like hospitals and transportation hubs along with offices and aeroplanes.
The Bubbler is essentially a glass tube with an attached glass pipette through which patients exhale. The tube contains reverse transcription reaction mixture and cold mineral oil.

The study's lead investigator William G. Fairbrother from Brown University in the US told MedicalXpress that "the Bubbler is more likely to be a better indicator of current infection than nasopharyngeal swabs."
