When to use
Use absolute counts and the trend, with left shift, atypia and morphology, to triage a white-cell abnormality.
How it works
Severe neutropenia: ANC < 0.5 ×10⁹/L; with fever = febrile neutropenia (emergency).
Key points
- Interpret absolute counts, not just percentages.
- Febrile neutropenia is an emergency needing empiric antibiotics.
- Peripheral blasts → suspect acute leukaemia, urgent haematology consult.
- Unexplained pancytopenia needs a marrow examination.
