Understanding Your Results

Results indicate the percentage of B-cells expressing CD79b. Abnormal levels may suggest B-cell malignancies, requiring further clinical correlation.
📊

Elevated CD79b expression

Possible B-cell malignancy such as chronic lymphocytic leukemia or lymphoma; recommend additional tests.

📊

Normal CD79b expression

No significant abnormality in B-cell markers; consider other causes if symptoms persist.

📊

Low or absent CD79b expression

May indicate certain B-cell disorders or technical issues; clinical review advised.

⚠️ When to Consult a Doctor:

If symptoms like fever, weight loss, or enlarged lymph nodes persist or worsen after test completion, or if results show abnormalities.

Limitations

  • ⚠May not detect all B-cell disorders
  • ⚠Requires integration with clinical history and other tests
  • ⚠Cannot distinguish between reactive and malignant conditions solely

Risks & Considerations
