B-cell leukemia/lymphoma panel

Table of Contents

Definition

B-cell leukemia/lymphoma panel is a test that looks for certain proteins on the surface of white blood cells called B-lymphocytes. The proteins serve as markers that may be helpful in diagnosing leukemia or lymphoma.


Alternative Names

B lymphocyte cell surface markers


How the test is performed

A blood sample is needed. For information on how this is done, see: Venipuncture

Less commonly, white blood cells are removed during a bone marrow biopsy. The sample may also be taken during after a lymph node biopsy or other biopsy when lymphoma is suspected.

The blood sample is sent to a laboratory, where the specialist checks the cell type and characteristics. This procedure is called immunophenotyping. The test is usually done using a technique called flow cytometry.


How to prepare for the test

No special preparation is usually necessary.


How the test will feel

When the needle is inserted to draw blood, you may feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.


Why the test is performed

This test may be performed:

  • When other tests (such as a blood smear) indicate abnormal white blood cells
  • When leukemia or lymphoma is suspected
  • To determine the type of leukemia or lymphoma
