Most patients never think about the laboratory. They see a doctor, give a blood sample, and wait for results. What happens in between, the analysis, the verification, the quality checks, the accreditation standards governing every step, is invisible to them. That invisibility is, in a sense, the goal. When clinical laboratory works the way it should, patients simply receive accurate results and the clinical decisions that follow them.
Rachel Azar has spent 23 years making sure that happens.
Her path into clinical laboratory was not accidental. It grew from genuine curiosity about the behind-the-scenes architecture of healthcare, shaped in part by the fact that her father held the same degree, though he never pursued it professionally. From her first role as a Medical Laboratory Scientist, she was struck by a reality that has never loosened its hold on her: every result generated in a laboratory has the potential to change someone’s life. That weight, she says, has stayed with her through every role, every initiative, and every quality system she has built or improved.
FROM CURIOSITY TO GREENFIELD
The moment that drew Rachel deeper into quality management was an early opportunity to work in a greenfield laboratory, a setting built from scratch where she was involved in implementing policies and procedures from the ground up. Most professionals inherit systems. Rachel helped create one. That experience gave her an unusually complete understanding of how quality infrastructure is assembled, and why the choices made at the foundation matter so enormously for everything built above them.
In 2005, she took the initiative to write her department’s safety plan, a decision that opened a door she has never closed. That early ownership of safety responsibilities evolved into a sustained commitment to laboratory, employee, and patient safety that now runs through every dimension of her professional practice.
Formal Lean Six Sigma training followed, along with accreditation expertise and health data management credentials. The accumulating qualifications were not credential-collecting. They were tools, each one acquired in service of a specific ambition: to build systems that prevent problems rather than simply identify them after the fact.
SIX ACCREDITATIONS AND WHAT THEY ACTUALLY MEAN
Among the milestones Rachel identifies as most significant, one stands out in scale and sustained effort: participating in and successfully achieving six consecutive JCI accreditations for her department over more than two decades at the same healthcare institution. That consistency across time, under evolving standards and shifting organizational conditions, represents something harder to achieve than any single certification.
She is clear about what accreditation actually demands from the inside. The process forces a laboratory to audit its own systems with genuine honesty, to find the gaps it did not know it had, to standardize practices that had drifted, and to retrain staff on policies that had faded into background noise. CAP and JCI standards compel an organization-wide quality consciousness that cannot be faked during an inspection because it must be lived continuously to survive one.
But the outcome she values most is not the certificate. It is the cultural shift that follows when accreditation preparation is done well. “Quality becomes a shared expectation rather than a top-down mandate,” she observes. That transformation in how a team understands its own work is, in her assessment, the real achievement.
LEAN SIX SIGMA AND THE DATA THAT TELLS THE STORY
Rachel describes Lean Six Sigma as fundamentally changing how she sees problems. Before the certification, she approached quality issues with intuition. After, she learned to slow down and let the data speak first.
In a laboratory environment, the DMAIC framework, Define, Measure, Analyze, Improve, Control, fits naturally. Laboratories are already data-rich environments. Adding a disciplined improvement structure creates the traction needed to translate data into meaningful change. She has used it to reduce turnaround times, decrease preanalytical errors, and streamline specimen processing workflows. Each improvement feeds directly into patient outcomes, because faster and more accurate results enable better clinical decisions.
What she values most in the methodology is its insistence on sustainability. The Control phase is not an afterthought. It is the point where an improvement becomes permanent, embedded into the system rather than dependent on the memory of the people who initiated it. That long-term thinking is precisely what healthcare quality requires, and precisely what short-term performance pressure often undermines.
SAFETY AS CULTURE, NOT COMPLIANCE
On the relationship between safety and organizational excellence, Rachel’s position is unambiguous. A laboratory where people feel safe to flag concerns, report near-misses, and question practices is one that continuously improves. A laboratory where people fear blame is one where problems stay hidden until they become serious, irreversible events.
Building the right culture begins with leadership response in the moment things go wrong. If the first instinct is to find fault rather than understand root causes, people will stop speaking up. Rachel’s consistent practice has been to approach safety events as learning opportunities, asking not “who is responsible?” but “why did our system allow this to happen?” Accountability matters, she is clear about that, but it operates most effectively within a system that first understands what failed and why.
She also points to the Lean principle of the Gemba Walk: leaders physically present on the floor, visibly engaging with safety practices, asking questions, taking feedback seriously, and demonstrating through daily behavior that safety is a genuine priority rather than a policy document. Culture is built in those daily moments, not in annual training sessions.
EFFICIENCY AND ACCURACY: NOT OPPOSITES
The tension between operational efficiency and quality standards is one Rachel navigates continuously, and she refuses to pretend it does not exist. Real pressure is applied to laboratories to do more with less, and that pressure can move in dangerous directions if quality is not actively protected.
Her resolution of this tension is both practical and principled. Efficiency and accuracy are not opposites. A well-designed process is almost always both faster and more accurate than a poorly designed one. Lean methodology has shown her repeatedly that waste and error typically share the same sources: unclear workflows, redundant steps, inadequate training, and poor communication. Address those, and throughput and quality improve simultaneously.
The critical discipline is knowing which steps must never be removed. Verification steps, quality control checkpoints, and independent review protocols exist because experience and previous incidents have demonstrated their necessity. Efficiency gains belong in the elimination of true waste, not in the shortcutting of safeguards. That distinction, she says, is exactly what Lean management means when practiced with integrity.
THE FUTURE SHE IS PREPARING FOR
Rachel’s fellowship with the American College of Health Data Management reflects her conviction that the next frontier of laboratory quality lies in predictive analytics: using historical data to anticipate equipment failures, predict staffing needs, and flag unusual result patterns before they reach the patient. That shift from reactive to proactive quality management is, in her view, where the field is heading and where its greatest potential lies.
To the next generation of laboratory and healthcare quality professionals, her advice is characteristically grounded. Get comfortable with data. Seek accreditation experience early. Find mentors and eventually become one. And above all, stay curious, because the professionals who will define quality and safety in the coming decade are those who are genuinely excited by change rather than unsettled by it.
Twenty-two years in, Rachel Azar remains exactly that kind of professional.
