This article was last modified on, formerly Lab Tests Online, was launched in 2001 by AACC—a global scientific and medical professional organization dedicated to better health through laboratory medicine. At that time, medicine was becoming more complex, and consumers were taking a greater hand in health care decision-making. AACC saw Lab Tests Online as a forum for individuals to learn about lab tests and have better conversations with their physicians.

Over time, 20 associations joined AACC in developing and reviewing all content onsite, which includes articles on lab tests, patient resources, and lab test news. This commitment to credible and clear health information led to at least 24 awards between 2002 and 2020 for excellence in promoting patient education and health literacy.

Eventually, Lab Tests Online expanded to more than 14 country sites and over 12 languages. Partnering organizations localized content to the national language, policy, and practice of their respective countries. Lab Tests Online set a global standard for patient engagement, attracting more than 470 million lifetime visitors.

In January 2021, AACC’s Lab Tests Online ( was acquired by OneCare Media. With this, OneCare moves to continue the site’s impressive growth and further nurture patient advocacy by coordinating with and expanding on its already impressive digital portfolio. Rebranded as, the site provides a unique resource for patients to help them access reliable testing options as well as information about tests. 

OneCare will rely upon a Medical Review Board to ensure that’s content continues to be science-based, accurate, and reflective of current data and findings.
