Lab Tests Online

Lab Tests Online is a peer-reviewed, patient-centered, non-profit web resource about clinical laboratory testing.^[1]^[2]^[3] The site provides information on clinical lab tests as well as conditions that are managed or diagnosed by lab tests.^[4] Lab Tests Online also provides summaries of recommendations by age, feature articles on lab-related topics, and news items of patient interest.^[5] All contents are reviewed and approved by an Editorial Review Board composed of laboratory professionals before being posted to the site.^[2]

The site was launched in 2001^[6] by the American Association for Clinical Chemistry,^[7] the scientific society for clinical laboratory science^[8] and is a collaboration of 17 other professional societies representing the laboratory medicine community.^[9] The website is available through 17 sites worldwide and via mobile apps in the U.S., the U.K. and Australasia.^[10]

As of 2012 the site received about 2 million viewers a month.^[11]
