Growing negative PR about LFD’s17 Feb 2021 15:12
We need a strong positive press campaign to counter the steady flow of negative press and PR material aimed at the general public to undermine confidence in LFD’s.
I received an unsolicited email this afternoon from a company called Euro Environmental with Benefits and Challenges of Rapid Antigen Tests in the subject line.

As an Avacta shareholder it caught my attention so I opened it. I was disturbed by the damaging, negative spin their article puts on the limitations of LFD's while they were heavily promoting the use of PCR testing of saliva samples.
“Although the majority of rapid antigen tests use nasopharyngeal specimens, some commercially available test kits utilise swabs taken from the lower nasal region which makes testing less invasive and more tolerable for patients than nasopharyngeal swabs. Nasal specimens from the nostrils provide similar information to those from the back of the nose (nasopharyngeal ) and throat (oropharyngeal), as long as the specimen is of good quality. This can help avoid the operational drawbacks because an individual will be more likely to collect a good sample without discomfort.”
PCR testing, on the other hand, can use a simple saliva test which is much easier to collect, provides more consistent and reliable specimens, and has much higher sensitivity (accuracy).
