RF Safe argues that red blood cell (RBC) “rouleaux” (stacking/aggregation) could be a visible, testable endpoint for investigating potential short-term physiological effects from wireless device exposure. The post highlights a 2025 report by Brown & Biebrich describing ultrasound observations interpreted as rouleaux-like aggregation after 5 minutes of smartphone placement near the popliteal vein, and contrasts this with earlier, more-criticized “live blood analysis” videos. It frames rouleaux as an electrostatic/zeta-potential phenomenon and calls for mechanistic testing and exposure mitigation, while presenting the ultrasound observation as a key shift toward more clinically standard imaging.

This RF Safe article discusses rouleaux formation (reversible red blood cell stacking) and proposes a speculative mechanism by which weak magnetic fields might influence red blood cell surface charge (zeta potential) via spin chemistry in heme-related radical-pair processes. The piece frames the idea as a mechanistic “what if?” rather than a direct claim that everyday phone use causes blood clotting, and it leans on general concepts from hematology and radical-pair magnetosensitivity (e.g., cryptochrome in animals). No new experimental data are presented in the provided text; the argument is largely theoretical and interpretive.
