B-cell receptor (BCR) mutation analysis (qualitative) for chronic lymphocytic leukemia (CLL) or other B-cell malignancies

Why This Test Might Be Ordered

Your doctor may recommend this test if you have symptoms of a blood disorder, such as persistent lymphadenopathy (swollen lymph nodes), unexplained fatigue, or an abnormal complete blood count (CBC). It’s often used in patients suspected of having CLL or other B-cell malignancies to confirm or refine diagnosis and treatment planning.

How the Test Works

Blood is drawn to collect a sample, which is then analyzed for specific mutations in the B-cell receptor genes. The test detects whether these mutations are present, helping to distinguish between different types of B-cell cancers.

Sample Collection and Preparation

A small amount of whole blood is taken from your arm. The blood sample is processed and sent to a lab for genetic analysis. No special preparation is needed, but fasting may not be required unless instructed by your doctor.

Test Results and Interpretation

Results are reported as either positive (mutation detected) or negative (mutation not detected). Your healthcare provider will interpret the results in the context of your clinical symptoms and other test findings to guide treatment options.
