Chronic Lymphocytic Leukemia (CLL)

Testing at ARUP Laboratories

Chronic lymphocytic leukemia (CLL) is characterized by small lymphocytes in the bone marrow, blood, and lymphoid tissues. CLL is the most common form of leukemia in adults in the U.S. and represents 40% of all adult leukemias in Western countries.

Cytogenetic, molecular, and flow cytometric testing play an important role in prognostication for CLL patients.
