Article 009: America Is in a Blood Crisis & O Negative Donors Are Needed Now!

Most of us never think about whether there will be blood waiting at the hospital when we need it. We simply assume it will be there.

Right now, that assumption is being tested.

On July 27, 2026, the American Red Cross declared a national blood supply crisis, only the second such declaration in its history. Blood donations have fallen to a four-year summer low, while demand from hospitals has increased during the summer trauma season. The situation has become serious enough that the Red Cross has begun limiting distributions of type O blood to hospitals.

This follows an emergency blood shortage declared earlier in July, when the Red Cross reported that its blood supply had fallen by nearly 25% during June while distributions to hospitals were running approximately 3,500 units per week higher than expected.

There have been many blood shortages and blood emergencies in the United States, so it would not be accurate to call this America's second blood shortage. What makes this different is that the Red Cross describes it as only the second national blood supply crisis it has declared in its history.

Why O Negative Blood Is So Important

All blood types are needed, but O negative has an extraordinary role in emergency medicine.

O negative red blood cells can be given to patients of any ABO/Rh blood type, which is why O negative is commonly called the universal red-cell donor type.

Think about what happens after a serious car accident, shooting, industrial accident or other catastrophic injury.

A patient can arrive unconscious and losing blood rapidly. Doctors may not know who the person is, much less their blood type. There are situations where there simply isn't enough time to wait before beginning a transfusion.

That's where type O blood becomes incredibly valuable.

O negative red cells can be used when a patient's blood type is unknown, giving emergency physicians an option while they are trying to keep that person alive.

And trauma is only one part of the story.

Blood products are routinely needed for surgeries, childbirth, anemia, blood disorders, cancer treatment and traumatic injuries. America's Blood Centers reports that approximately 11 million blood transfusions occur each year for patients suffering from many different conditions.

The blood you donate could eventually help a mother experiencing catastrophic bleeding during childbirth.

It could help someone injured in a car accident.

It could support a cancer patient going through treatment.

It could help someone undergoing major surgery.

It could help a person living with a serious blood disorder.

Or it could be hanging in an emergency room when someone arrives with only minutes to spare.

You may never know who receives your blood. But to that person and their family, having blood available can mean everything.

Why Are We Running Out of Blood?

There isn't one single reason.

According to the Red Cross, donations have fallen to a four-year summer low while hospital demand has increased during the summer trauma season. Extreme heat, poor air quality and widespread foodborne illnesses have also contributed to lower donor turnout this summer.

The problem is that blood isn't something hospitals can simply manufacture when supplies get low.

The system depends on people continuing to walk through the doors of blood centers and voluntarily donating.

And the demand doesn't stop.

People don't stop getting cancer because donations are down.

Babies don't stop being born.

Surgeries don't disappear.

People with blood disorders still require treatment.

Car crashes and traumatic injuries still happen.

Blood centers therefore have to maintain a supply capable of handling both everyday medical needs and unexpected emergencies.

The O Negative Problem

For those of us in the Rh-negative community, there is an additional reason to pay attention.

There simply aren't that many O negative donors compared with the number of situations in which O negative blood can be useful.

When blood supplies become strained, that creates a difficult equation: a relatively small donor population supplying one of the most versatile red-cell types in emergency medicine.

The current shortage isn't theoretical, either. The Red Cross says it has already begun limiting distributions of type O blood to hospitals.

That should get our attention.

We spend a lot of time discussing Rh-negative genetics, history, pregnancy, transfusion medicine and what makes Rh-negative blood different.

But there are moments when having an Rh-negative blood type becomes more than something interesting to discuss.

This is one of those moments.

Don't Trust the Red Cross? You Have Other Choices.

We also need to address something that may keep some people from donating.

Not everyone trusts the American Red Cross.

Some people have concerns about large organizations. Others would rather know that they're supporting a community organization or a particular hospital. Whatever someone's reason, distrust of one organization does not mean they have to sit out during a blood shortage.

The Red Cross does not control America's entire blood supply.

There is a large network of independent, community-based blood centers operating throughout the United States.

In fact, America's Blood Centers says its independent member blood centers collectively provide close to 60% of the U.S. blood supply. They operate more than 700 blood collection sites in more than 1,100 communities and provide blood products and services to more than 3,500 hospitals and healthcare facilities across North America. Its U.S. members are regulated by the FDA.

So if you don't want to donate through the Red Cross, you don't have to.

You can look for an independent community blood center in your area. Depending on where you live, there may also be hospital-based donation programs or other regional blood organizations.

You can also ask questions before donating.

Ask which hospitals the organization supplies. Ask how donated blood is processed and distributed. Ask whether it is nonprofit. Find an organization you feel comfortable supporting.

The goal shouldn't be to convince everyone to trust one particular organization.

The goal is to make sure a patient doesn't die because the blood they needed wasn't available.

America's Blood Centers provides a tool for finding independent community blood centers around the country:

This Isn't Only About O Negative

Our community naturally has a particular interest in Rh-negative blood, but we shouldn't give people the impression that other blood types aren't needed.

They absolutely are.

The current crisis affects the larger blood supply. Type O is under particularly severe pressure, but patients need blood and blood components from donors of many different types.

So share this with your O positive, A, B and AB friends too.

A healthy blood supply depends on a broad and consistent donor population.

Community blood centers alone report that approximately 33,000 blood donations are needed every day to meet patient needs among the communities they serve.

Imagine If It Were Someone You Loved

It's easy to scroll past another headline saying there's a blood shortage.

But imagine the situation differently.

Imagine you're standing in an emergency room and it's your child, your mother, your father, your brother, your sister or your best friend who is bleeding.

The doctors know exactly what they need to do.

The equipment is there.

The surgeons are there.

The nurses are there.

The hospital is there.

But the blood isn't.

At that moment, blood donation stops being an abstract public-health issue.

You would hope that somewhere, sometime during the weeks before that emergency, a stranger rolled up their sleeve.

Our Community Can Actually Do Something

The Rh-negative community is spread throughout the United States and around the world.

Normally we come together to discuss our genetics, our history and the science surrounding our blood.

Today I'm asking our community to do something more practical.

If you're eligible to donate blood, consider donating.

If you trust the Red Cross, donate through the Red Cross.

If you don't trust the Red Cross, find an independent community blood center or another donation program you do trust.

If you're O negative, understand just how valuable your red cells can be during an emergency.

And if you can't donate, you can still help by sharing the message with someone who can.

This isn't about supporting an organization.

It isn't about politics.

And it isn't about convincing people to agree about everything surrounding the blood industry.

It's about making sure blood is there when another human being needs it.

Somewhere in America, someone is going to wake up today with absolutely no idea that before the day is over, they may need another person's blood to stay alive.

They won't know the donor's name.

They won't know their politics, their background or their beliefs.

They may never meet them.

But because someone decided to donate, they may get to go home.

That's why we need donors.

And right now, we need them badly!
