Diagnosis of PV
Blood tests provide the primary information necessary to diagnosis PV. Patients may also undergo a bone marrow examination. PV typically involves a high concentration of red blood cells and the presence of certain gene mutations in blood cells.
Treatment of PV
Treatment of PV can improve symptoms and and reduce the risk of complications. Choice of treatment depends in part on a patient’s risk of blood clots. 3 Patients who are older or who have history of blood clots are considered high-risk and may require more extensive treatment than patients who are low-risk.
Management of PV that Progresses to Myelofibrosis or Acute Myeloid Leukemia
In rare cases, PV progresses to myelofibrosis (scarring of the bone marrow) or acute myeloid leukemia (AML). Among people with PV, the 10-year risk of myelofibrosis is less than 10% and the 10-year risk of AML is less than 5%. 2 For information about the management of these conditions, click on one of the following:
