I am not too impressed with today's RNS. The last para starts out with giving numbers (16 out of 40) that's less than 50%.
'In addition, under the clinical trial supervision of the Royal College of Surgeons, Ireland, 40 subjects, 16 of which were independently confirmed as COVID19 positive with PCR[iii] tests, provided breath samples that were tested on the Microtox® BT nano-optofluidic chip surface with Affimer® reagents ("Avacta Group")[iv] and Optimers ("Aptamer Group")[v] together the ("Binding Agents").
The breath samples detected binding on the nano-optofluidic chip with a secondary antibody to the Spike Protein which was initially selected for the isolated spike protein work. Detection of the live virus was confirmed indicating 9 times increase in the digital spectrum signal on the Microtox® BT when compared to controls of nano-optofluidic chips with binding agent; and 19 times increase in signal with nano-optofluidic chips without binding agents. Additional digital background noise was indicated due to the non-specific binding of the antibody. Further data is required to confirm the same high sensitivity and specificity is achieved on breath test clinical trials which are underway.'
These sentences don't tell us how many of the 19 who tested positive by other methods ALSO tested +ve by DVRG method!
Am I missing something?
