The advantage of breath testing is that it is non-invasive and non-intrusive,” said Dr. Dweik. “It does not have a dose limitation like x-rays, an amount limitation like blood or saliva tests, or a timing limitation like PCR, blood and urine tests. So, breath testing can be performed repeatedly as needed. This technology has the potential to make COVID-19 testing more accessible and rapidly available as well as to guide critical therapeutic decisions.”
