In Honor of Cathryn

You can help this little fighter!

Cathryn, a brave 10-year-old, was diagnosed with a blood disorder and autoimmune disease that caused her to have a stoke and seizure. She needed blood and platelet transfusions to help her.

Cathryn's Journey

After months of misdiagnoses, she was diagnosed with thrombocytopenia and p-ANCA microscopic polyangiitis, and severe anemia requiring multiple blood transfusions, chemotherapy, and plasma exchanges to survive.

Despite the challenges, Cathryn remains strong and resilient, facing her treatments with a positive outlook. “Other kids could have it worse,” she says, showing incredible strength throughout her journey.

"Without it, I don't think she would have lived."

For more than 45 years, the nonprofit South Texas Blood & Tissue Center has focused on a critical purpose: to save and improve lives.

Inspired by a group of physicians, our organization was formed to provide blood to the South Texas region – ensuring a safe and adequate blood supply through proper testing, storage and distribution to hospitals. This essential service allows front-line workers to focus on the direct care of patients, with confidence that this lifesaving resource will be there when it’s needed most.

But we didn’t stop there. Over the years, we’ve evolved as the needs of our patients and hospitals have changed, driven to save lives in as many ways as possible.

We couldn’t do this without donors like you. We understand that the gift of donation is a personal, powerful choice that has the potential to touch a life. Today, we offer many ways to make a difference that include:

Our team has also expanded its programs, partnering with leaders within the healthcare industry to develop a wide range of therapies.
