What makes this even more revolutionary to me (retired anesthesiologist) is that the methodology allows for use of Theranos-style finger-prick-size blood samples rather than IV blood draw, since fragment identity is the indicator rather than level/concentration.

The concentration of cell free DNA in blood plasma is generally in the nanograms/mL range, meaning most cfDNA assays will require at least a ~mL of plasma input for sufficient sensitivity / reproducibility. We aren’t quite at the capillary blood level of sensitivity yet.
