Washington, DC, June 30, 2011      The American Association for Clinical Chemistry (AACC) announces that the 2010 Thomson Reuters Impact Factor, released on June 28, increased AACC’s flagship journal Clinical Chemistry’s Impact Factor to 6.886 from 6.263 in 2009. This places Clinical Chemistry in the top 3% of all published journals, with an Immediacy Index of 1.769, placing it in the top 2.5% of all journals. The 2010 Impact Factor reflects the performance of the journal in 2008-09 and is a quantitative measure of the performance of a journal calculated by dividing the number of citations received during a two year period by the number of citable items published in the same two years.

In recognition of these achievements, and also the journal’s introduction of innovative content, Clinical Chemistry received an APEX 2011 Award of Excellence in the “Most Improved Magazine or Journal” category. APEX Awards are conferred based on excellence in design, editorial content and overall communications excellence.

Clinical Chemistry is published by AACC from its offices in Washington, DC. The journal’s Editor-in-Chief is Nader Rifai, PhD, of the Children’s Hospital and Harvard Medical School in Boston, MA, who is supported by a Board of Editors drawn from laboratories and institutions in the United States and throughout the world. Commenting on the news, Dr. Rifai issued the following statement:

“It is gratifying that Clinical Chemistry has seen its Impact Factor increase, confirming the journal’s position as the leading forum for peer-reviewed, original research on innovative practices in today’s clinical laboratory, and the most cited. Our editorial team strives to publish the most relevant, topical, and influential research in the field of laboratory medicine. The Board of Editors and I appreciate the creativity of our contributors and the continued loyalty of our readers. This increase in Clinical Chemistry’s Impact Factor confirms that contributors, editorial team, and publishing team are achieving our goal. I look forward to continuing improvements in the stature of Clinical Chemistry in 2011.”
