DENVER, Colo. (Feb. 25, 2026) — The American Red Cross urges donors to help the national blood supply recover from a severe blood shortage and empower their health by making an appointment to give blood in March. As a thank-you for helping save lives, successful donations will receive free A1C testing, commonly used to screen for prediabetes and diabetes, in March (one result per calendar year).

New Red Cross data reveals 1 in 5 blood donors have elevated A1C levels — a sign that prediabetes and diabetes are prevalent among adults in generally good health. The findings are based on the first year of free A1C screening offered by the Red Cross, which provided results to more than 920,000 blood donors nationwide over three testing periods in 2025. Among donors with elevated A1C levels, 80% had readings indicating prediabetes — a condition that can often be reversed through lifestyle changes such as a balanced diet and regular exercise.

"Too many people still face gaps in access to preventive care, and the Red Cross is proud to help close them by giving our 2.5 million blood and platelet donors easy access to essential health information, like their blood sugar levels," said Dr. Courtney Lawrence, Red Cross medical director. "By giving blood and downloading our Blood Donor App, individuals can be informed and empowered to better manage and advocate for their health."

The A1C test does not require fasting and provides an average blood sugar level over the past three months. Visit RedCrossBlood.org, use the Red Cross Blood Donor App or call 1-800-RED CROSS to schedule your March donation appointment. All who come to give blood, platelets or plasma March 1-31, 2026, will also receive a $15 Amazon Gift Card by email. See RedCrossBlood.org/March for details.

Donating blood in March is part of Red Cross Month, a national campaign that encourages people to deliver support when help can’t wait by also making a financial donation, volunteering or taking a lifesaving skills class.

Why You Should Know Your A1C

Millions of U.S. adults are living with undiagnosed prediabetes and Type 2 diabetes, which are often preventable and in many cases, reversible. These conditions often develop silently, though if untreated, they can lead to serious health complications such as stroke, heart disease and kidney failure.

Early detection isn't just good for long-term health — it's also a warning for people’s wallets.

An American Diabetes Association study found that, while people with prediabetes typically incur a few hundred dollars in additional medical costs each year, those with blood sugar levels that have progressed to the diabetic range could face several thousand dollars more in annual expenses — as much as 25 times higher.

How to Find Out Your A1C from the Red Cross

After making a successful blood donation in March, donors can access their A1C result within one to two weeks through the Red Cross Blood Donor App or donor portal at RedCrossBlood.org. Anyone with an elevated A1C level is encouraged to consult their health care provider.

In addition, donors can access and track their blood pressure, hemoglobin, pulse and body temperature, which are taken during each donation's mini‑physical to ensure they’re healthy enough to give.

How Blood Donation Can Help Bridge Health Care Gaps

As the nation's largest blood supplier, the Red Cross is uniquely positioned to help bridge existing health care gaps by providing blood donors with critical health insights. Through the Red Cross Blood Donor App and online donor portal, donors can track their results and share them with their health care provider.

These efforts are part of the broader Red Cross mission, which has supported the health of communities for 145 years. Today, across Colorado — from Grand Junction, Durango and the Western Slope to the Denver metro, from Fort Collins, Greeley and the Eastern Plains to Colorado Springs, Pueblo and the San Luis Valley — this work includes installing free smoke alarms in neighborhoods at high risk for home fires; providing basic health and mental health services to disaster survivors; and supporting the well-being of military families, veterans and their caregivers.

Frequently Asked Questions

Q: Why is the Red Cross testing blood donors' A1C levels?

A: The Red Cross values the health and well-being of blood donors. By providing this vital health insight, the Red Cross is helping to bridge existing care gaps and empower donors to take an important step toward preventative care and lifesaving intervention.

Q: Should I fast to receive the A1C test on my blood donation?

A: No, the A1C test does not require individuals to fast. This is noteworthy because eating a nutritious meal prior to blood donation is important.

Q: Can I donate blood if I have prediabetes or diabetes?

A: People with prediabetes or diabetes are generally eligible to donate blood if they are feeling well on the day of their donation. In most situations, the type of medication donors take to manage their diabetes does not disqualify them from donating blood.

Q: Can I donate blood while taking GLP-1 medication?

A: In most situations, the type of medication you take to manage your diabetes or insulin resistance won't disqualify you from donating blood. Whether you take insulin injections like Apidra or Humalog, an injected diabetes medication like Ozempic or Mounjaro, or oral medications like metformin, you are still eligible to donate if you are feeling well on the day of your donation.
