Understanding Erythrocytosis Basics
- Erythrocytosis means raised hematocrit with too many red blood cells.
- It includes relative (low plasma volume) and absolute (increased red cell mass) forms.
Ask About Aquagenic Pruritus
- Ask about aquagenic pruritus by specifically inquiring if itching occurs after a shower or bath.
- This symptom often precedes polycythemia vera diagnosis by up to three years.
Confirm Absolute Erythrocytosis First
- Always confirm if erythrocytosis is absolute by checking hydration status.
- Repeat blood tests if results are unexpected before further workup.
