We see more and more bio-tech companies like Helix promoting 'clinico-genomic' data: they are inseprable from big-data and big-tech providers.
Helix offers Covid Testing. A new source of profit. PCR tests have been discredited due to 97% false positives: (countries using 30 - 45 cycle process), which its inventor Kary Mullis said was not suitable for detection. Still we see big-bio-tech cashing in on this 'demand' led by governments and now employers, and airlines as we move towards more restrictions without testing.
The DNA is an amplification test and not meant to be used to indicate infection. The side effect of his experimental testing was to duplicate the signal. He was looking for something else.
