Secondary Polycythemia: Causes, Treatment, Symptoms, and More
When this happens, the bone marrow can no longer produce enough healthy blood cells. Experts refer to this condition, which is a type of chronic leukemia, as myelofibrosis . It can sometimes lead to acute myeloid leukemia, though this is rare.
In patients diagnosed with idiopathic erythrocytosis, if the hematocrit is above 54%, then reduced to a target of 50% may be considered. For patients with comorbid conditions predisposing to a thrombotic risk and ischemia, a lower target of 45% may also be considered if already greater than 54%. In this specific group of patients, cytoreductive therapy is contraindicated. Patients usually have nonspecific symptoms on the presentation that include fatigue, headache, and dizziness. In some cases, due to the hyperviscosity of blood, transient ischemic attacks lead to a transient visual defect.
Can i donate blood if i have polycythemia or is it considered "tainted"?
A simple blood test administered by physicians can measure complete blood count. Primary polycythemia and secondary polycythemia are similar. However, the former starts inside the bone marrow , whereas the latter starts outside of the bone marrow. Still, in both conditions, the normal bone marrow is overstimulated to overproduce red blood cells.

Usually you’ll have an excess of the hormone erythropoietin that drives the production of red cells. Before donating blood, please refer to your state’s or public health agency’s guidelines for COVID-19 testing and quarantining. Do not come to donate if you have symptoms of COVID-19 or are subject to quarantine after close contact with individuals diagnosed with or suspected of having COVID-19 infection. If you’ve had COVID-19 and have been symptom-free for 10 days, you are eligible to donate. Correcting or eliminating the cause of secondary polycythemia is the most important aim of treating blood-related abnormalities.
