WBC Differential Interpretation

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.
