Specialist in Cytometry Exam

The ASCP is now offering a “Specialist in Cytometry” (SCYM) which has taken the place of the previous Certification in Cytometry (CCy) and Qualification in Cytometry (QCYM)

Beginning October 1, 2017, the ASCP BOC, in conjunction with the International Society for Advancement of Cytometry (ISAC) and the International Clinical Cytometry Society (ICCS), will be offering a Specialist in Cytometry (SCYM) certification.

New Specialty in Cytometry
The International Society for Advancement of Cytometry (ISAC), the International Clinical Cytometry Society (ICCS) and the American Society for Clinical Pathology Board of Certification (BOC) have reached an agreement to develop, administer, and maintain a new conjoint credential in Cytometry to be issued by the BOC. This new credential was launched in the Fall of 2017, and will replace both the ICCE (CCy) and the QCYM (ASCP) recognition programs. By combining forces for this new credential, the three societies will be able to increase the impact of cytometry certification in clinical and research fields around the world.

“ASCP BOC’s involvement in the cytometry certification program will strengthen the credential and the field of cytometry,” said Paul Wallace, President of ISAC. “ASCP BOC can open doors to the possibility of state licensure for certified cytometrists that ISAC and ICCS cannot do on its own.”

“ASCP is the world’s largest professional membership organization for pathologists and laboratory professionals. Having a Specialty that includes their endorsement will bring a high recognition factor to the cytometry credential,” said Bruce Greig, Chair of the ICCE certification advisory committee and member of ICCS.

“ISAC and ICCS have proven that there is a worldwide demand for a cytometry certification program” said Pat Tanabe, Executive Director, ASCP Board of Certification. “Combining our Qualification in Cytometry with the ICCE certification program will increase our impact in the field of cytometry.”

With the new ASCP BOC Specialty now in place, the ICCE program and the QCYM will be discontinued.  All current holders of either the CCy or QCYM credential will be grandfathered into the new ASCP BOC Specialty in Cytometry without taking the new Cytometry Exam and at no additional cost. The ASCP will be contacting all current certification holders with details about the change.  Additional details of the changes regarding the new Specialty and more information on the new exam can be found online:

ISAC and ICCS, with generous support from the Wallace H. Coulter Foundation, developed and launched the International Cytometry Certification Examination (ICCE) program in September 2011 to benefit cytometrists around the globe. That support will continue with the new credential to now be offered by ASCP BOC.


The International Clinical Cytometry Society (ICCS) serves the needs of those involved in current and emerging clinical applications of cytometry throughout the world, through advocacy, scientific meetings, the Journal Cytometry Part B (clinical cytometry), educational courses and on-line materials.

The International Society for Advancement of Cytometry (ISAC) is a global scientific society with more than 1700 members in 52 countries. Its mission is to serve a multidisciplinary community by leading technological innovation, scholarship, and the exchange of knowledge in the quantitative cell sciences, and its vision is to advance the impact of cytometry in meeting current and emerging challenges in the life, biomedical, and physical sciences.

As the oldest and largest certification agency for laboratory professionals, the ASCP Board of Certification (BOC) has certified more than 500,000 individuals both in the U.S and internationally since it was established, and has become the gold standard for certification of laboratory personnel. The mission of the Board of Certification is to provide excellence in certification of laboratory professionals on behalf of patients worldwide.

The Board of Governors (BOG) of the BOC is composed of representatives from many laboratory professional organizations. The BOC brings together perspectives and expertise of laboratory professionals from many different organizations, institutions and geographic locations to address the certification needs of practitioners at all levels of practice.
