• 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.
