Acute Undifferentiated Leukaemia (AUL): diagnosis


To diagnose acute undifferentiated leukaemia the cells need to meet specific criteria, and possible alternatives should be excluded. These are given in the table below:

Requirement 1
No lineage can be assigned by lineage-defining markers of myeloid, B-lymphoid or T-lymphoid lineage

Review Criteria:

Requirement 2
Ensure that other conditions that may resemble undifferentiated acute leukaemia are excluded: particularly consider whether marker patterns suggest any of the following:
Requirement 3
Consider whether the case may be better described as Acute Leukaemia of Ambiguous Lineage - not otherwise specified (ALAL-NOS) - see guidance
