Closing the Loop: Blood Donation as a Doorway to Primary Care

Blood centers now hand donors real health data, including A1C, cholesterol, blood pressure, and hemoglobin, and then the data dies in an app. This is an open proposal for a 100 donor pilot that routes those measurements to the donor's own physician. It is offered freely to any blood center and health system that will run it.

What Is Already Happening

The American Red Cross returned A1C results to more than 920,000 donors in 2025. One in 5 were in the prediabetic or diabetic range, and 80 percent of those were in the prediabetic range, which is largely reversible when it is caught. Several other large blood centers in the United States now return cholesterol or A1C to donors, and nearly every center returns blood pressure, hemoglobin, and pulse.

Every one of these programs stops at the donor portal. None routes results to a physician. A March 2026 paper in the journal Transfusion, on wellness testing in blood donation, warns that portal only results create donor anxiety, unnecessary follow up, and questions that blood center staff cannot answer, and it calls for a physician anchored model. The National Heart, Lung, and Blood Institute is already funding a precedent: a trial that uses donor cholesterol screening to connect donors with likely familial hypercholesterolemia to care. That trial runs through cardiology for 1 condition. No program yet routes a donor's ordinary results to the donor's own primary care physician.

The Proposal

One hundred consenting adult donors at 1 or 2 donor centers who are already primary care patients of a partnering health system. With a separate written authorization, a short list of measurements from their donation is transmitted securely to their own physician: blood pressure, pulse, and hemoglobin, which the center already takes, plus inexpensive add ons such as A1C, a lipid panel, and ferritin. The physician reviews, orders confirmatory testing when a value is actionable, and follows up. No diagnosis is ever made on a screening value alone. No infectious disease result and no genetic result is ever included. Outcomes are tracked for 180 days and published whatever they show.

The pilot is designed as research so that the results can be published and so that any later blood center and health system pair can run the identical plan and pool results. A full feasibility analysis covers the regulatory path under HIPAA, CLIA, FDA rules, and state law, the comparable programs in the United States and abroad, the pilot and research design, the data architecture, costs, funding paths, and a timeline. A statistical analysis plan and common data model define, before any participant is enrolled, what will be measured, how a previously unknown and clinically actionable finding is decided, and what the results will be compared against. Every claim in those documents is tagged verified, inferred, or unverified.

What It Costs

The planning estimate is $110,000 to $175,000 for 100 donors, much of it absorbable in kind by a health system that already has the laboratory, the electronic health record, and research compliance staff. Add on testing is roughly $15 to $30 per donor in reagents, or close to zero if the health system's own laboratory runs an extra tube.

Why the Order Publishes This

The Order's Pillar of Enlightenment holds that knowledge which stops in 1 person saves no one. A result that reaches a physician can save a life. A result that stops in an app cannot. That is the whole argument, and it is why the Order does not hold this work back. The analysis is offered without restriction and may be used, changed, or republished by anyone. The author asks for no money, no staff, no role, and no compensation. The goal is that this gets built, first somewhere, then everywhere.

If you run a blood center or a health system and want the full feasibility analysis, the statistical analysis plan, and the concept note, write to hello@soemt.org. When a first pilot is agreed, the partners will be named here with their consent, and the results will be published on this site as they come.

This note is a research proposal, not medical advice. A screening value from a blood donation is not a diagnosis. Anyone with a concerning result should speak with their physician.
