  • Blood loss
    • Anemia (various types)
    • Hemorrhage
  • Bone marrow failure (for example, from radiation, toxin, fibrosis, tumor)
  • Erythropoietin deficiency (secondary to renal disease)
  • Hemolysis (RBC destruction)
  • Leukemia
  • Multiple myeloma
  • Malnutrition (nutritional deficiencies of iron, folate, vitamin B12, or vitamin B6)
Low numbers of WBCs (leukopenia) may indicate:
  • Bone marrow failure (for example, due to infection, tumor or fibrosis)
  • Presence of cytotoxic substance
  • Autoimmune/collagen-vascular diseases (such as lupus erythematosus)
  • Disease of the liver or spleen
  • Radiation exposure
High numbers of WBCs (leukocytosis) may indicate:
  • Infectious diseases
  • Inflammatory disease (such as rheumatoid arthritis or allergy)
  • Leukemia
  • Severe emotional or physical stress
  • Tissue damage (SUCH AS burns)
Low hematocrit may indicate:
  • Anemia (various types)
  • Blood loss (hemorrhage)
  • Bone marrow failure (for example, due to radiation, toxin, fibrosis, tumor)
  • Hemolysis (RBC destruction) related to transfusion reaction
  • Leukemia
  • Malnutrition or specific nutritional deficiency
  • Multiple myeloma
  • Rheumatoid arthritis
High hematocrit may indicate:
  • Dehydration
    • Burns
    • Diarrhea
  • Polycythemia vera
  • Low oxygen tension (smoking, congenital heart disease, living at high altitudes)
Low hemoglobin values may indicate:
  • Anemia (various types)
  • Blood loss
The test may be performed under many different conditions and in the assessment of many different diseases.
