100% detection and quantification of SARS-CoV-2 with PBM-HALE, in 1 minute of exhaled breath, requires forced expiration and gives Ct's as low as 25.8. We have updated our preprint with the interim data from our Brazil study 1/n https://t.co/dgDvNwQD4e
Our Pre-print on exhaled breath detection of COVID-19 and bacteria from your lung. TL;DR summary: you do not emit any virus if you are infected, have symptoms, and are breathing in a relaxed fashion.
This DOES NOT mean COVID-19 isn’t airborne 1/n https://t.co/JftiNsHjUk
@drkristenkc Cytokine data was also obtained in the second study, but normalisation factors and assay optimisation are required for better interpretation. Correlation work with tidal samples also requires longer sampling 17/x
We've uploaded a pre-print focused on our 2 clinical studies with PBM-Hale on noninavsive sampling the lower-lung without saliva contamination for pathogen detection. This is an update to the 2022 preprint with the whole development story of PBM-Hale. 1/x

@drkristenkc Main limitations: these were observational small-sized studies looking at percent positive agreement to nasopharyngeal swab positivity. The n number is small, & false negative rate within each study was not determined. 16/x
🔥 Researchers have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils. This surprising discovery sheds new light on how our immune system works, particularly during allergic reactions. 1/
