The World’s Leading Authority for Chronic Lymphocytic Leukemia Patients

Abbreviations & Acronyms

In science and medicine, information is constantly changing and may become out-of-date as new data emerge. All articles and interviews are informational only, should never be considered medical advice, and should never be acted on without review with your health care team.

It would be unrealistic to expect any newly diagnosed patient to understand all of the abbreviations and acronyms that can be encountered when first learning about CLL. This handy reference sheet will familiarize you with abbreviations and acronyms that are most frequently used.
