AACC is an international society comprised of medical professionals with an interest in clinical chemistry, clinical laboratory science, and laboratory medicine. Founded in 1948, the society has over 8,000 members and is headquartered in Washington, DC.

What is Clinical Chemistry?

Clinical chemistry is what goes on when you have your blood tests done at the doctor's office, and it also involves medical testing performed on other human fluids. Basically, clinical chemistry is medical testing that uses chemical processes, with those results applied to evaluating patient health.

Today, clinical chemistry plays an essential role in disciplines such as cardiac care, cancer testing, prenatal testing, diabetes management, infectious disease testing, maternal care, blood banking, genetic testing, and customized medicine. 

AACC represents not only the medical professionals who perform these analyses, but also the innovators who design, manufacture, and sell the devices utilized in clinical laboratory science. Advances in laboratory testing made by AACC members enable physicians to make earlier diagnoses, tailor individualized therapy for patients, and develop improved disease management strategies.

Nearly half, (48%) of AACC members hold doctoral degrees, typically PhD and/or MD. Fifteen percent have MS, MA or MBA degrees; 27% have BS or BA degrees. AACC members come from 109 countries, with 27% of the membership residing outside the U.S.

AACC is subdivided geographically into 20 local sections. Members can also choose to join any of the 17 divisions segmented according to areas of interest. The association is governed by a Board of Directors that is elected by the membership.

Government Affairs

AACC conducts a comprehensive government affairs program, maintaining communication between our members, Congress, the Executive Branch, the Centers for Medicare and Medicaid Services, the Food and Drug Administration, the Centers for Disease Control and Prevention, and other federal agencies with a stake in the clinical laboratory.


AACC sponsors dozens of scientific conferences each year, the largest and most prestigious of which is our Annual Meeting and Clinical Lab Expo. First held in 1949, this educational meeting and technology exposition is the leading event in the clinical laboratory profession, attracting nearly 20,000 participants.

Our Clinical Laboratory Expo is the world's largest trade fair dedicated exclusively to clinical laboratory science, with over 1,900 booths and more than 700 participating companies.

AACC also sponsors the Arnold O. Beckman Conference; the Oak Ridge Conference on Advanced Analytical Concepts for the Clinical Laboratory; Laboratory Automation conferences in the U.S., Europe, and SE Asia; the Clinical Chemistry Review Course; and a host of audioconferences and webinars on clinical, regulatory, and management topics.


AACC issues six periodicals, and is also a major publisher of books on clinical laboratory science and practice.

Clinical Chemistry
AACC's peer-reviewed, flagship publication is the most-cited journal in the field. It's available in print as well as online. Readers can earn continuing education credits by studying selected articles each month.

Clinical Laboratory News
Features in-depth analysis of scientific and regulatory developments affecting clinical laboratories with in-depth articles on important new developments in lab testing.

Clinical & Forensic Toxicology News
Provides practical and timely information on the clinical, forensic, technical, and regulatory issues faced by toxicology laboratories.

AACC also offers the online publications AACC eNews, Government Affairs Update, and Clinical Laboratory Strategies.

In addition to periodicals, AACC Press publishes numerous books and reference guides for clinical laboratorians, medical libraries, and students of laboratory medicine. AACC Press publishes an average of ten books a year, and we currently offer over 300 titles through our catalog.


AACC offers career information and accredited continuing education in clinical laboratory science using publications, meetings and distance learning technology. We also sponsor the Commission on Accreditation in Clinical Chemistry (COMACC), which is an independent non-profit organization that accredits training programs in clinical chemistry at the masters, doctoral, and postdoctoral levels.

Student Travel Grants
AACC's Directed Donations Program funds travel grants to students to help them defray the cost of attending the AACC Annual Meeting. Students must have authored an accepted abstracts describing their research.

Genzyme Student Research Awards
Students with accepted abstracts are encouraged to present their scientific research at AACC's Annual Meeting during the student research awards contest. The awards are funded by a generous gift from Genzyme to AACC's Directed Donations Program. EDU

Special Features and Programs

Awards and Grants
AACC recognizes and celebrates outstanding contributions through a strong awards program. Most awards go to individuals in the field of laboratory medicine, but some, such as the lectureship award, are often given to noteworthy people from other disciplines. AACC presents twelve awards each year with financial support from the clinical laboratory industry. For information on award winners and how to nominate deserving lab professionals, go to the AACC Awards web site

Directed Donations Program
The Directed Donations Program is AACC's philanthropic program. Its purpose is to encourage excellence in science and raise interest in the practice of clinical laboratory medicine.

Society for Young Clinical Laboratorians (SYCL)

AACC's Society for Young Clinical Laboratorians (SYCL) supports the unique needs of younger AACC members. SYCL provides early-career members practical advice on such things as preparing for board exams, landing a new job, and securing travel grants. SYCL members enjoy a dedicated listserv as well as a quarterly podcast series, SYCL360, to keep SYCL members up to date on the latest SYCL information. SYCL's Mentor of the Month series offers career advice, and the SYCL Seminar Series promotes the field of Clinical Laboratory Medicine to young scientists. There is no application or fee to join;  AACC automatically enrolls members under the age of 40, as well as those in training programs. Click here for more information.

Global Initiatives

One of AACC's strategic initiatives is to advance the international presence of the association and develop programs that support the global laboratory community. To that end VSF administers an International Travel Grant program, as well as an AACC Membership Grant program funded by generous contributions from longtime AACC member Dr. Jerry Gallwas and his wife Sandy. In addition, Gallwas award winners are offered professional resources such as books, magazine subscriptions, and conference registration at no charge or at reduced price.
