Laboratory findings associated with the diagnosis of myeloproliferative neoplasm include leukocytosis, thrombocytopenia, and anemia.

Laboratory Findings

Laboratory findings associated with myeloproliferative neoplasm include:[1][2][3][4][5][6]

  • Blood chemistry
  • The following blood levels may be elevated:
  • Bleeding and clotting factors
  • The following blood parameters may be elevated:
  • Flow cytometry helps determine the type of cells that are present.
  • Chromosome changes that may occur in some people with leukemia include:
  • Similar to cytogenetics, but more specific for particular chromosomal translocations
  • Polymerase chain reaction
  • Helpful to detect specific abnormalities in blood or bone marrow cells. Abnormalities can be found even if very few leukemia cells are present in a tissue sample.
  • Neutrophil alkaline phosphatase level
  • Vitamin B12 (or B12 binding capacity) level
  • Erythropoietin level
  • Molecular testing for JAK2, CALR, and MPL mutations
