Meet Abby Carroll,MS-CLS, MLS (ASCP)cm, a clinical laboratory professional who has spent the last eight years working at the bench, supporting clinicians, and now advancing the future of diagnostic stewardship as a resident.

Abby began her career as a , rotating through immunohematology, hematology, and clinical chemistry in fast-paced clinical settings. She’s managed complex antibody investigations, interpreted challenging hematology differentials, and ensured accurate, timely results during some of the most critical moments in patient care.

As her career evolved, Abby realized her passion wasn’t only in generating results, it was in helping clinicians understand and use those results effectively.

That drive led her to pursue the Doctor of Clinical Laboratory Science (DCLS) at Rutgers University, where she now serves as a resident focused on diagnostic stewardship and evidence-based laboratory practice.

From crossmatches to clinical consults, Abby’s journey illustrates how modern laboratory professionals are shaping the future of patient-centered care.

Meet Heidi Schutz, a lab professional whose career spans , , information systems, and leadership across both clinical and community settings.

Heidi began her journey in clinical laboratory science with a focus on hematology and transfusion medicine, later expanding her expertise into laboratory information systems. Her work in a hematology/oncology practice honed her phlebotomy and patient-centered skills, giving her a deep appreciation for how accurate diagnostics directly impact care.

After taking time to focus on family, Heidi returned to the bench in family medicine, where she quickly advanced into leadership roles that strengthened her regulatory and management expertise. She later re-entered the hospital environment, managing point-of-care testing technologies that improved workflow efficiency and patient outcomes.

Today, Heidi brings her cross-disciplinary experience to the non-profit sector, supporting initiatives that expand access to laboratory testing in under-served communities and during disaster relief efforts. Her work reflects a lifelong commitment to equitable healthcare and the critical role of diagnostics in every patient’s story.

When we talk about diagnostic safety, we often start with data.
But this time, the data starts with patients.

A new open-access study in Frontiers in Public Health amplifies the voices of nearly 4,000 Americans who shared their experiences with diagnostic problems — from missed tests to delayed diagnoses.

Their stories reveal a powerful truth:
> 38% experienced at least one diagnostic problem in four years
> Younger adults ( Cis-women, transgender and gender-independent individuals, multiracial patients, low-income households, and people with disabilities reported the most harm.

These findings remind us that diagnostic equity isn’t just a goal — it’s a measure of trust.
