Point of care testing is urgently required to enable the immediate detection of SARS-CoV-2 infection to allow effective transmission prevention precautions to succeed.
The Coronacheck device is a hand-held, portable, point-of-care device which will allow the
safe collection of EBC. It provides an automated platform for the detection of SARS-CoV-2
using an existing sensor repurposed with immobilised recombinant ACE-2 to bind the virus.
This produces a measurable signal indicating whether SARS-CoV-2 is present or not.
EBC is collected by the CoronaCheck device during tidal breathing, making this investigation
non-invasive, repeatable and easy to perform. Previous studies using Inflammacheck™ in people
with respiratory conditions have shown it is well tolerated, even in people with severe lung
disease. The full test cycle including sample collection and test assay typically occurs in
less than 5 minutes.
Given the risk of infection, this CoronaCheck™ device has an integrated sensor and breath
collection system combined in a fully enclosed, disposable unit to mitigate the risk of
cross-infections between users and also reduces any exposure risk to healthcare staff. It is
appreciated that disposable plastic has a negative environmental impact, however due to the
highly contagious nature of SARS-CoV-2 it is felt unavoidable at present.
Using the CoronaCheck does not require laboratory equipment or expertise, and is a quick,
easy-to-use point-of-care investigation which provides an immediate result. This could
potentially be applied to screening for SARS-CoV-2 in a wide variety of environments for
example: GP practices, drive-thru centres, colleges, universities, airports and sports
arenas.
Any person undergoing a swab for a possible SARS CoV-2 infection is eligible for inclusion,
participants will not be assigned an intervention.
The participants will breathe into the CoronaCheck device. This involves breathing for up to
6 minutes into a single use, fully sealed unit attached to the hand-held device. This
disposable unit has a bacterial-viral filter attached to both the breathing inlet and the
exhale outlet to eliminate any risk of contamination. The CoronaCheck device then provides a
reading reflecting EBC ACE2 binding which will be documented on the eCRF. This result will
not be recorded in the clinical notes as it is not intended to inform patient management
decisions in this study.
