CD20

CD20 measures the presence and quantity of CD20 protein on B cells in your blood. Monitoring CD20 levels assists in evaluating the immune system's function and response to certain conditions. Higher levels of this protein may indicate certain types of B cell lymphomas or leukaemias.

This test is done primarily to:

• Evaluate B-cell-related disorders like lymphomas and leukaemias
• Assess response to therapy for autoimmune diseases affecting B cells
• Guide treatment plans for conditions like rheumatoid arthritis
• Monitor immune system health in various diseases
• Determine effectiveness of specific medications targeting CD20

Your healthcare provider may recommend this test:

• To diagnose and monitor B-cell-related disorders
• If you have an autoimmune disease affecting B cells
• When managing conditions like rheumatoid arthritis
• For assessing immune system health in certain diseases
• If your doctor prescribes medications targeting CD20

• Elevated or reduced levels may suggest B-cell disorders, autoimmune conditions, or inadequate immune function.

Abnormal results require further evaluation by your doctor to determine underlying causes and appropriate management.

This test requires a blood sample.

During the test:

• A sample is collected using a needle inserted into a vein.
• The process is quick and relatively painless.
• Minimal discomfort might be experienced during blood draw.

There are no specific preparations required for the test. However, it is recommended that you consult with your healthcare provider before taking the test, as they may have specific instructions or recommendations based on your individual medical history and current health status.

Other tests include:

• B Cell Panel Testing: Evaluates additional markers on B cells to aid diagnosis.
• Rheumatoid Factor Testing: Detects antibodies associated with autoimmune diseases like rheumatoid arthritis.

• B-Lymphocyte Antigen CD20 
• Leukocyte Surface Antigen Leu16

Lymphoma is a type of cancer that originates in infection-fighting cells called lymphocytes. Two main types of this condition are Hodgkin's lymphoma and Non-Hodgkin's lymphoma. It usually involves lymph nodes, but it can affect other parts of the body where lymphocytes are found. Symptoms may include swollen lymph nodes, fever, fatigue, and weight loss.
