Why Become a CLSI Member?

Confidence in Compliance
CLSI guidance is the gold standard for laboratory and diagnostic testing. Recognized by accrediting bodies and regulatory agencies worldwide, our consensus-based documents ensure laboratories meet ISO, CAP, FDA and Joint Commission (JCC) requirements with clarity and confidence.
Risk Reduction & Cost Savings
Implementing CLSI standards streamlines workflows, minimizes errors, and strengthens quality management systems. Members gain access to tools and training that reduces costly mistakes and supports efficient operations.
A Seat at the Table
CLSI members participate in document development committees, expert panels, and working groups, giving them a voice in defining the protocols that laboratories and regulators follow. CLSI's consensus-based process brings together health professions, industry, and government leaders, ensuring that CLSI members are not just following best practices—they’re helping define them.
Global Recognition and Reputation
CLSI standards are used in laboratories across the globe - from hospital systems and public health laboratories to academic institutions and industry leaders. Our members display their CLSI member logo and credentials with pride, signaling their commitment to quality, innovation, and leadership.
Commitment to Patient Safety
From specimen collection to reporting results, CLSI standards and protocols guide every step of the process and testing environment. Our resources help laboratories meet patient safety goals and deliver timely results that improve diagnosis and care.
“All of the analytical testing that goes into the verification and validation activities of our laboratory diagnostic products are based on our internal quality procedures which in turn are based on CLSI documents.”
Jim Pierson-Perry
Siemens Healthcare Diagnostics
“Our clinical partners like to hire our students. The students are more work-ready because of the training we do, utilizing the CLSI standards. The guidelines help the students acclimate really easily.”
Tywan Banks
Columbus State Community College
"Of course we use ISO standards but we [also] need standards that are more specific for each discipline and that is what we get from CLSI…. In every Canadian lab you are bound to see at least one CLSI standard being referenced in their procedures.”
Anne Marie Martel
Ordre Professionnel des Technologistes Médicaux du Québec (OPTMQ)
"CLSI Health System membership is beneficial to us because it allows greater access to all CLSI documents by all our staff and it promotes participation in CLSI education programs."
Diana L. Kremitske, MS, MHA, MLS (ASCP)
Diagnostic Medicine Institute, Geisinger
"One of our strategies is to operate as a system. That is how we stay patient-centered and deliver quality … We had robust quality systems but we were functioning as independent silos. We wanted to standardize our approach to quality and processes. This is where CLSI has come in."
Jeanna Houseman, MHSA, DLM(ASCP)CM
HealthPartners
"Our quality management system is based on the CLSI model so CLSI is very important to our organization. The guidelines are frequently used to develop, implement, and provide continual improvements to our laboratory services."
Danielle Trembla
Nova Scotia Health Authority
"CLSI is a source of vetted information we know we can trust."
Shannon Bennett
Mayo Clinic
"Our organization has always prided itself in the Quality Care we offer. CLSI has been a great resource in helping us to keep up with the latest procedures and standards that have been vetted by the top specialists in the field."
Kristen Brooks
Northridge Hospital
"CLSI documents are the building blocks for the Laboratory so to speak, any area of the laboratory that needs information for improving processes CLSI has a document that will support those efforts."
Kathy Nejezchleb
CommonSpirit Health
"CLSI documents are now part of our continuous education platform and a reason why we achieved a continuous exemplary (JCI/CAP) accreditation since 2014 till this year."
Gilrose Brinas-Bautista, RMT, AMT
Hamad Medical Corporation
"CLSI is essentially our ‘Bible’ for quality. The standards we base all of our policy on."
Terri Philpot
Tenet Health System
