For many people, the work of medical laboratory professionals happens out of sight. But every test run, every label checked, and every unit carefully handled plays a direct role in saving lives. During Medical Laboratory Professionals Week, April 20–26, we pause to recognize these dedicated teams and the impact they make every day.

For Edward “Eddie” Marchese, that impact has been felt for more than four decades.

Eddie has spent 42 years with the American Red Cross and currently serves as a Quarantine and Labeling Supervisor. When asked why he’s stayed so long, his answer is simple and powerful.

“I get satisfaction knowing that I’m doing something to help save lives,” he said.

That mission has guided Eddie from the very beginning. He started his Red Cross career in hospital services before being invited to work in the lab. What began as a new opportunity quickly became a lifelong calling. Over the years, as operations expanded and departments evolved, Eddie found his home in quarantine and labeling, a vital area that ensures only safe, high-quality blood products reach patients in need.

While many people may never see the lab side of lifesaving work, Eddie and his colleagues understand the responsibility that comes with it.

“Everything we touch here,” Eddie said, “there’s a life on the other end of it.”

That understanding shapes every day in the lab. Accuracy matters. Precision matters. Behind every careful step is a person waiting for care, a patient whose life may depend on what happens behind the scenes.

One moment early in Eddie’s career cemented that reality forever.

A baby urgently needed a fresh unit of blood. Nurses reached out to the staff working that night, asking if anyone could donate immediately. Eddie didn’t love needles — and still doesn’t — but he stepped forward. His blood type was a match, and he donated.

Days later, he learned the baby was doing well.

“That joy,” he said, remembering the moment, “was a really good feeling for me.”

It was more than a moment of pride. It became a turning point, a reminder of why the work matters, even when it’s challenging, even when it’s hard.

“That was pretty much what set it off for me,” Eddie shared. “I’m here for life.”

Throughout his career, what keeps Eddie coming back every day hasn’t changed.

“I come here and do what I can,” he said, “to make sure that we’re getting the best product out there to help save lives.”

During Medical Laboratory Professionals Week, Eddie’s story reflects the dedication of thousands of Red Cross laboratory professionals across the country. These teams may work quietly, but their impact is anything but small. From ensuring blood safety to supporting patients they will never meet, their work makes countless moments of hope possible.

To every laboratory professional who shows up day after day with care, precision, and purpose — thank you. Your work saves lives, and this week, we proudly recognize you.
