Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All subjects will be asked to donate 4-6 teaspoons of blood. On occasion, if the blood cells from a particular sample do not grow well and the DNA from that sample is used up or other tests are needed, we may ask to collect additional samples. In patients who have undergone a bone marrow biopsy as part of their clinical evaluation, we will test the reproducibility between pathologists for the revised 2008 WHO diagnostic criteria to diagnose myeloproliferative disorders (MPD).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Affected Population
Patients suspected to have one of the following blood disorders: polycythemia vera, myelofibrosis or essential thrombocythemia.
No interventions assigned to this group
Healthy Female Controls
Healthy females who do not have the blood disorders; Polycythemia Vera, Essential Thrombocythemia and/or Myelofibrosis.
No interventions assigned to this group
Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Patients with a persistent thrombocytosis (\>400,000) that does not have an obvious secondary cause
3. Patients with a bone marrow biopsy that shows increased cellularity and fibrosis
4. Patients where there is clinical concern for primary myelofibrosis, such as anemia in combination with leukocytosis, thrombocytosis, splenomegaly and/or a leukoerythroblastic blood smear
5. Patients with thrombosis at unusual sites, such as Budd-Chiari syndrome, can have early PV before hemoglobin is elevated, these patients will also be included.
Exclusion Criteria
2. Subjects with a known acquired cause of thrombocytosis.
3. Subjects will be excluded if they cannot demonstrate decision making capacity sufficient to agree or decline the blood drawing or use of their blood for the study.
