CD markers play a crucial role in identifying cell lineage and diagnosing hematological malignancies through flow cytometry.
Some commonly used markers:
🔹 CD34+ → Blast cells
🔹 CD3+ → T-cell lineage
🔹 CD19+ → B-cell lineage
🔹 CD33+ → Myeloid lineage
Common Associations:
• CD34+ CD19+ → B-ALL
• CD34+ CD3+ → T-ALL
• CD34+ CD33+ → AML
• CD34− CD33+ → APL
These markers are essential in differentiating acute leukemias and guiding accurate diagnosis and treatment strategies in clinical hematology.
Flow cytometry remains one of the most powerful diagnostic tools in modern laboratory medicine and oncology.
