Table: Marker patterns that allow definite assignment of acute myeloid lineage
| Pattern 2: At least two myeloid lineage-associated markers are present and there are no lineage defining markers of T or B cells and no more than one T-cell or B-cell lineage-associated marker is present | |
| CD117 | An early marker of myeloid lineage, seen in up to 80% of AML and vauable in recognising more primitive differentaiion forms (note that aberrant expression is seen in up to 20% of ALL cases) |
| CD33 | A good marker for AML, particularly for those cases with granulocytic maturation, CD33 is often less strongly expressed in AML with monocytic dfferentiation and strongly expressed in APL. |
| CD13 | A good lineage marker for AML that is acquired a little later in differentation than CD117 or CD33; expression of CD13 is often higher than CD33 in AML with monocytic differentiation. |
