Everything begins with a blood smear or bone marrow aspirate. Under the microscope, a pathologist looks for "blasts"—cells that have lost their way. Are the cells abnormally large? The Nucleus: Is the chromatin clumped or fine? The Clues: Presence of Auer rods or specific granules.

The true power lies in the overlap. A pathologist might see "monomorphous medium-sized blasts" (Morphology) and use Flow Cytometry to confirm they are actually "CD10+ B-lymphoblasts." Everything begins with a blood smear or bone marrow aspirate

Morphology can suggest a lineage, but it cannot always prove it. Two cells might look identical but behave like total strangers. The Molecular Fingerprint (Flow Cytometry) The Nucleus: Is the chromatin clumped or fine

It detects "CD markers" (Clusters of Differentiation). CD34: Signals a primitive, immature cell. CD19/CD20: Confirms a B-cell lineage. CD13/CD33: Points toward myeloid involvement. The Synthesis: A Final Diagnosis
