The Secret Life of Plasma in a Wretched Economy

ESSAY | The duality of the Liquid Gold

Diluted seawater has nearly the same concentration of elements and minerals as blood plasma. —Nnedi Okorafor

Cielo

The almost 17,000 square feet BioLife facility in Duluth, Georgia, sits in a busy strip mall off one of the city’s busiest roads. As a hive of nurses and phlebotomists dart between oversized lounge chairs and whirling white apheresis machines, I find my way to the waiting area. These devices systematically collect blood, separate the plasma from red blood cells and platelets using a centrifuge, then return the blood components to the donor in a process called plasmapheresis.

When I arrived on a recent Tuesday afternoon, the waiting room was full, and on a far wall stand dozens of would-be donors waiting to be screened (a finger prick, blood pressure check, and body temperature) before donating plasma.

Eyeing the donors, I notice they are men and women aged nineteen to sixty-plus. Most looked like typical students, while others appeared weary and dressed in construction work clothes. There were dress suits, hoodies, boots, fancy dress shoes, and medical professionals in scrubs. All the faces seemed to have the same vapid expression, as though they were all lost in a forest and something was chasing them, but they didn’t care.

Many seem to know each other. An obese Black man using a cane hobbled over to an empty chair.

“Hey, man,” he says to a college-age kid, then pauses because he’s out of breath. “I’m back. Gots to get that cash and eat. Didn’t see youz last week, where you be?”

The polite kid smiled. “Monday-Friday last week. You good, Cielo?”

Cielo grins with infectious energy. “It all good,” he says.

A Quiet Understanding of Necessity

Sonya Rache clasps her hands together on the white desk and squeezes her fingers tightly. “This is the first time I haven’t worked two or three different nursing jobs,” she tells me. “But now, this economy. We just don’t know what’s next.”

Sonya is the charge nurse overseeing new donors at BioLife. In her late forties, her Indian American complexion seems to glow under the fluorescent lights of her stark white office. She looks tired, and the clinic’s chaotic pace suggests she’s likely overworked.

She tells me to place my left thumb over a scanner to confirm the information I gave her.

“Ready to go down the rabbit hole? This is how donors sign in when they donate.”

I nod. I asked her what types of people she sees donate, even though I got a preview of the waiting room earlier.

“I’ve seen all of humanity. Lawyers, doctors, teachers, people with PhDs, single parents." She adjusts her thick black glasses and purses her lips. “Then there are the folks trying to eat. That’s the thing about plasma. It’s a quiet understanding of necessity.”

The Science of Plasma and How It Became an Industry

Blood plasma, when separated from blood, forms the pale-yellow liquid portion and accounts for around 55% of its total volume. Composed of 92% water, it carries essential nutrients, proteins, electrolytes, and hormones that transport particles, regulate pH, and support immune function. A centrifuge (apheresis machine) separates plasma from blood cells by spinning the blood at high speeds, forcing the denser red blood cells downward and leaving the plasma on top. It looks like this:

Blood drawn → spun → plasma separated → red blood cells returned to body

While blood banking began in the 1930s after hospitals learned to store and separate blood components, the primitive methods of separating the plasma were laborious. After collecting blood in tubes with anticoagulants, practitioners manually centrifuged and extracted the plasma using a syringe.

During World War II, the importance of human serum albumin for battlefield casualties—just one of many vital components of plasma—proved invaluable. For severe blood loss injuries, albumin increases blood volume to maintain osmotic pressure in the body, yet albumin had to be separated from the plasma on the spot.

The method of isolating serum albumin fraction from blood plasma using cold ethanol (a process still in use today) was the brainchild of Dr. Edwin Cohn, and medical aids performed it on battlefields for rapid separation of blood plasma for quick administration.

By the 1950s, researchers discovered something unique, something that shifted donor plasma to supply chain: humans could safely donate plasma up to twice weekly.

The Liquid Gold

Plasma is big business. Pharmaceutical manufacturing integrates with plasma collection companies, and they don’t merely collect plasma—they convert it into lucrative biologic drugs. The Takeda Pharmaceutical Company, which operates BioLife, has a global hub and research center in Cambridge, MA., with sites spanning the U.S. in thirty-nine states.

Because plasma transforms into lifesaving therapies for people with unusual and complex incurable diseases, the medical field demands it, and manufacturers cannot synthetically produce it at scale. The answer? Paid donors.

Only a few countries allow paid plasma donations, making the U.S. the major global supplier. While plasma donation in the United States flourished in the 1960s and 70s because of the evolution of plasmapheresis and the rising demand for chronic disease therapies, paid donations scaled after 2006. Plasma donation centers expanded across the U.S., and by 2023, over 1,200 plasma centers strategically appeared in suburban and lower-income neighborhoods near pawn shops and payday lenders.

That market strategy works because it’s a lure for struggling households, and that’s the dichotomy: plasma donors are often financially challenged, while recipients rely on plasma for survival.

Reimbursement for Lost Time

Plasma donors receive payment for the inconvenience of time and not necessarily for the plasma, with the average donation taking around one to two hours depending on fluid flow (the more hydrated you are, the faster it goes).

Separated plasma, once fractionated (processed into the different key products for multiple therapeutic uses), is worth thousands of dollars per patient dose. Growing demand for immune disorders, emergency trauma care, and rare, incurable diseases keeps the market value higher every year. Products derived from plasma include:

•          Immunoglobulins (IVIG) (immune deficiencies, autoimmune diseases)

•          Albumin (burn casualties, trauma patients)

•          Clotting factors (hemophilia patients)

Because plasma companies depend on consistent donors, they offer payments of roughly $50–100 per visit to keep people coming back. Across regions, many donors are under thirty-five, financially underwater, jobless, lacking savings, or navigating limited access to credit. Single parents and gig workers often rely on the income to fill paycheck gaps. Some studies suggest Black and Hispanic men emerging disproportionately among regular donors—not because plasma centers target any one group, but because economic uncertainty rarely occurs equitably across a city.

While plasma donation through non-profits such as the Red Cross is mostly altruistic-based, at for-profits like BioLife, donors survive on the “payroll.” Donations cover groceries and utilities or help pay the rent—and often donations help fill the void of paying for medications or food.

The weekly donations also help many avoid predator payday loans, where money is “borrowed” early against salaries. When plasma centers emerge in urban areas, payday loan usage drops. A University of Colorado study identified that young adults are 18% less inclined to seek payday loans after a plasma center opened nearby. Researchers contrasted the effect to raising the minimum wage by approximately $1 per hour locally.

Because over two-thirds donate to meet basic living expenses, plasma donation becomes routine survival behavior. Given that the plasma industry reportedly grew more than 30% since 2022 and Americans made around 75 million plasma donations in 2025—an average of more than 200,000 each day—it’s predicted that those numbers will expand again in 2026. In the U.S., five dollars a gallon gas, unaffordable healthcare, and outrageous grocery prices make plasma donation a valid option.

While the numbers show a painful reality, what Sonya Rache already sees is a cultural shift in who is donating. Middle-class, laid off professionals, individuals with PhDs and other advanced degrees, and even employed workers who still can’t make ends meet have superseded a younger population.

As I leave the facility that afternoon, the waiting room is at capacity because the machine respects everyone equally.

Cielo hobbles at the door as I hold it for him. A bright green gauze tape wraps around his elbow where the needle sat in his vein for hours. He nods to me.

“’bout dinner time, ain’t it?” he says.
