Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9] [10]
In oncology, polycythemia vera (PV) is an uncommon myeloproliferative neoplasm in which the bone marrow makes too many red blood cells. [1] The majority of cases [2] are caused by mutations in the JAK2 gene, most commonly resulting in a single amino acid change in its protein product from valine to phenylalanine at position 617.
[15] [16] [17] Patients are usually designated as having a low or high risk of bleeding or developing blood clots based on their age, medical history, blood counts and their lifestyles. Low risk individuals are usually treated with aspirin , whereas those at high risk are treated with hydroxycarbamide , interferon-α or anagrelide ).
ICD-10 coding number Diseases Database coding number Medical Subject Headings Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state ...
Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. [4] An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is called polycythemia. [5] Both are potentially life-threatening disorders.

Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are single-gene disorders and, in most cases, they are inherited as autosomal co-dominant traits.
Hematological values such as hemoglobin, hematocrit, and red blood cell counts are elevated in patients with myomatous erythrocytosis syndrome. [3] The diagnostic criteria for myomatous erythrocytosis syndrome includes polycythemia, uterine myoma, and return of hemoglobin levels to normal following fibroid excision surgery. [10]
