Rethinking ESR: The Nussbaumer Method for Measuring Plasma Creation, Not RBC Sedimentation

Updated: Jul 30



The Erythrocyte Sedimentation Rate (ESR) has long been used as a nonspecific marker of inflammation by measuring the rate at which red blood cells settle in a vertical tube of blood over time. While ESR remains an established clinical tool, the Nussbaumer Method proposes a different perspective—one that focuses not on the movement of red blood cells, but on the biological processes occurring within the plasma.


Plasma: Creation, Not Separation

Conventional hematology describes plasma as the liquid component of blood that becomes separated from blood cells during centrifugation or sedimentation. The Nussbaumer Method presents an alternative hypothesis: that plasma should be investigated as a dynamic biological creation in response to physiological stress, rather than viewed solely as a component being separated from whole blood.

This concept can be summarized as "creation, not separation."


According to this developing hypothesis, cellular stress—whether resulting from physical injury, chemical exposure, environmental influences, infection, or other physiological challenges—initiates what I describe as a "calcium ion crisis." This proposed response involves the rapid mobilization of intracellular calcium ions, potentially contributing to the biological processes that create and modify plasma composition during the body's response to injury.


Rather than viewing plasma as a static component waiting to be isolated, this hypothesis suggests that the plasma layer reflects an active and ongoing biological response occurring throughout the body.


Looking Beyond Red Blood Cell Sedimentation

Traditional ESR measures the rate at which erythrocytes settle through plasma. The Nussbaumer Method proposes that equal attention should be given to the creation and evolution of the plasma layer itself.


Instead of focusing exclusively on red blood cell sedimentation, this hypothesis suggests investigating:

  • The rate of plasma creation.

  • Changes in plasma volume.

  • Plasma viscosity.

  • Dynamic changes in plasma composition during systemic stress.

  • The relationship between plasma formation and calcium-mediated cellular signaling.


Within this proposed framework, the biologically meaningful event is not simply the settling of red blood cells. It is the creation and transformation of plasma occurring above them.


Expanding Diagnostic Possibilities

If future research supports this hypothesis, measuring plasma creation alongside traditional laboratory markers could provide additional insight into inflammatory processes, vascular disease, metabolic dysfunction, and immune activation.

The Nussbaumer Method does not seek to replace established laboratory testing. Rather, it proposes an expanded framework for investigating blood physiology by examining plasma creation, not simply plasma separation, as a potential indicator of the body's response to injury and disease.


A Call for Scientific Investigation

The concepts presented here represent a developing scientific hypothesis and should not be interpreted as established medical fact or clinical guidance. Laboratory research, imaging studies, and prospective clinical trials will be necessary to evaluate the proposed mechanisms and determine their biological and clinical significance.


Advancing our understanding of blood physiology requires the willingness to examine new ideas through rigorous scientific investigation. Researchers, clinicians, engineers, and academic collaborators interested in studying plasma biology, calcium signaling, vascular physiology, and diagnostic innovation are encouraged to explore these concepts as this work continues to evolve.
