What Does My Cytometry Test Report Indicate?

Question: Hello,

I recently had flow cytometry test done on Peripheral blood. Reason for the test was mildly elevated relative lymphocyte count. The Absolute count was fine. Below is the report of the Flow cytometry. I would like to have it reviewed by a Hematologist.

Also I would like to know what does the following line mean: "Monocytes co-express CD14 and CD64 without phenotypic abnormalities.". Are CD14 and CD64 normally expressed in monocytes?

Report is here:
F Flow Cytometry Interpretation See Below For Report
- Peripheral Blood
- Diagnosis:
- No diagnostic immunophenotypic abnormalities detected (see comments).
- Comments:
- No immunophenotypic evidence of a lymphoproliferative disorder, acute leukemia or circulating
- blasts is identified. Myeloproliferative neoplasms and myelodysplastic syndromes may not show
- antigenic abnormalities on myeloid cells and cannot be ruled out by flow cytometry. Please
- correlate the result with morphological findings, other pertinent laboratory data and clinical information.
- Flow Differential (%) and Population Analysis:
- Lymphocytes: 39.6%
- T-cells (71% of lymphoid cells) show a CD4/CD8 ratio of about 1.2 without overt
- phenotypic abnormality. NK-cells (11% of lymphoid cells) are unremarkable. Mature B-cells (15% of
- lymphoid cells) are polyclonal (kappa:lambda 1.6).
- Monocytes: 5.1%
- Monocytes co-express CD14 and CD64 without phenotypic abnormalities.
- Granulocytes: 51.7%
- Granulocytes are phenotypically mature and without aberrant antigen expression.
- Specimen Viability: 99.7%
- Cell Yield: 4.2 Million
- Markers Performed:
- CD2, CD3, CD4, CD5, CD7, CD8, CD10, CD11c, CD13, CD14, CD16, CD19, CD20,
- CD23, CD33, CD34, CD38, CD45, CD56, CD64, CD117, HLA-DR, Kappa, Lambda (24 Markers)

Thank you Dr XXXXXXX I am an anxiety disorder patient and tend to over analyze the results. So your answer helps a lot. One followup question. Does this flow cytometry test also detect Multiple Myleoma? I'm not sure why i'm fixated with that.

I understand that the B cells looked normal and polyclonal, which is a good indication. But still a confirmation from an expert like you help.

Thank you,

Thank you Dr XXXXXXX for your response. I have two followup questions if you dont mind (for sake of my peace of mind).

1) I understand flow cytometry would not be used to diagnose myeloma. But would it show some abnormalities if there was myeloma? The flow cytometry report mentions "Mature B-Cells which are polyclonal" and the "kappa:lambda 1.6". I have read on the internet that in cases of myeloma these will not be the case. Is that correct? Also my doctor had done eGFR and metabolic panel tests (including albumin) and all those reports came back fine.

2) Also you said my blood count does not indicate myeloma. Does that mean in case of myeloma, the WBC/RBC counts are way higher of way lower?

Sorry for the barrage of questions even after you said everything is normal and there is no need to worry. Unfortunately have partial information from the internet which stokes my anxiety. Your response would be helpful.

Thanks,

Kartik

Thank you Dr XXXXXXX That was helpful. I realize its my anxiety which makes me overthink all these. Thanks for your patience.
