Polycythemia (Elevated Haematocrit)


North South North West Statewide

Pre-referral work-up


Polycythemia is a primary or secondary phenomenon.

Secondary causes of polycythemia generally relate to smoking or other chronic lung pathologies.  Consider referral to Respiratory Clinic for the primary condition.

Primary polycythemia (myeloproliferative neoplasm: polycythemia vera) should be considered in the presence of splenomegaly.

All referrals should comply to referral standards and include in particular:

  • Relevant investigations, including previous results to assess temporal pattern
  • Relevant clinical findings including splenomegaly


  • Jak-2 (positive) and erythropoietin (low/low-normal) are useful blood tests to further investigate suspected primary polycythemia
    (Jak-2 negative polycythemia is rare)
