The RBC size distribution curves reliably distinguished between thalassemia minor and polycythemia with iron deficiency. To confirm a diagnosis of erythrocytosis, a blood sample (taken without a tourniquet, if possible) is required. This may limit or retard further erythropoiesis so that additional phlebotomies may not be necessary. Polycythemia vera (PV) is characterized by erythropoiesis and JAK2- activating mutations, with increased risks of morbidity and mortality. Adults with polycythaemia secondary to cyanotic congenital heart disease may be at greater risk from injudicious venesection than from their polycythaemia.1 Despite an established literature on the subject, patients are frequently put at risk from acute volume depletion and chronic iron deficiency… Continued blood withdrawal will worsen the iron deficiency; iron supplementation will … Treatments led to a hematologic response, albeit with minimal improvement in fatigue, may!
