The Spin

Techno-skeptic narrative

The Theranos scandal proves that claims about blood testing using tiny samples are dangerous pipe dreams. Physical limitations make it scientifically impossible to detect multiple biomarkers from blood drops, since most disease markers are present at extremely low concentrations. Relying on small sample diagnostics leads to misdiagnosis and delayed treatment.

Techno-optimist narrative

Pinprick blood tests are revolutionizing healthcare by predicting diseases up to 10 years before symptoms appear. Scientists can now measure thousands of proteins and molecules from a single drop, creating accurate risk signatures for cancer, heart disease and dementia. This breakthrough shifts medicine toward prevention rather than reactive treatment.
