Understand your lab tests,
understand your health.
At Kareem, we help individuals advocate for their health by providing learning guides and products that make lab testing accessible, convenient, and affordable.
The History of Kareem
Kareem, formerly Lab Tests Online, was launched in 2001 by AACC—a global scientific and medical professional organization dedicated to better health through laboratory medicine. Our foundation is built on the belief that access to information is the first step toward better care.
Lab testing provides the data you need to build and maintain a care plan that is as custom and convenient as possible. Today, we host over 400 expert-reviewed lab test guides to help you understand what each test measures, how it’s used, and when you might need it.
We turn information into action. By partnering with certified laboratories, we provide a secure experience for ordering tests directly. Most results are ready within 1-2 days, allowing you to make informed healthcare decisions with clarity and confidence.
"It’s all about the data."
