Overview: CD79a Flow Cytometry Test
Introduction: The CD79a Flow Cytometry Test detects CD79a markers to diagnose lymphoma, causing swollen lymph nodes or fever. Aligned with 2023 ASH guidelines, it uses flow cytometry for high specificity, aiding in cancer screening. This test is critical for guiding diagnosis, treatment, and improving outcomes in hematology for patients with suspected lymphoma. Other Names: CD79a Flow Assay, B-Cell Receptor Test. FDA Status: Laboratory-developed test (LDT), meeting hematology standards for diagnostic accuracy. Historical Milestone: CD79a testing began in the 1990s with lymphoma research. Flow cytometry emerged in the 2000s, improving accuracy for marker detection. Purpose: Diagnoses lymphoma, guides treatment, and monitors CD79a markers in patients with swollen lymph nodes or fever. Test Parameters: 1. CD79a Pretest Condition: No fasting required. Collect whole blood or bone marrow at any time. Report symptoms like swollen lymph nodes or fever, and list medications. Specimen: 2-5 mL whole blood (EDTA) or 2-5 mL bone marrow (EDTA). Transport in a biohazard bag within 24 hours. Sample Stability at Room Temperature: 24 hours Sample Stability at Refrigeration: 48 hours Sample Stability at Frozen: Not frozen Medical History: Document swollen lymph nodes, fever, or history of lymphoma. Include current medications, especially chemotherapeutics. Consent: Written consent required, detailing the tests purpose, diagnostic implications, and potential need for cancer therapy. Procedural Considerations: Uses flow cytometry to detect CD79a markers. Results are available in 1-2 days, enabling rapid clinical decisions. Factors Affecting Result Accuracy: Poor sample quality or low cell yield can affect results. Non-malignant conditions may express CD79a. Clinical Significance: Positive CD79a expression suggests lymphoma, prompting treatment. Negative results may require additional marker testing. Specialist Consultation: Consult a hematologist or oncologist for result interpretation. Additional Supporting Tests: Bone marrow biopsy, other flow cytometry markers (e.g., CD19, CD20), or PET scan to confirm lymphoma. Test Limitations: Non-specific expression may occur in non-malignant conditions. Results require clinical correlation. References: ASH Lymphoma Guidelines, 2023; Blood, Swerdlow SH, 2022. |
