CBC
Alternative names:
complete blood count
Normal values:
- RBC (varies with altitude):
- male: 4.7 to 6.1 million cells/mcl
- female: 4.2 to 5.4 million cells/mcl
- WBC: 4,500 to 10,000 cells/mcl
- hematocrit (varies with altitude):
- male: 40.7 to 50.3 %
- female: 36.1 to 44.3 %
- hemoglobin (varies with altitude):
- male: 13.8 to 17.2 gm/dl
- female: 12.1 to 15.1 gm/dl
- MCV: 80 to 95 femtoliter
- MCH: 27 to 31 pg/cell
- MCHC: 32 to 36 gm/dl
Note: cells/mcl = cells per microliter; gm/dl = grams per deciliter; pg/cell = picograms per cell
What abnormal results mean:
High numbers of RBCs may indicate: Low numbers of RBCs may indicate: Low numbers of WBCs (leukopenia) may indicate: - bone marrow failure (for example, due to granuloma (granular tumor), tumor, or fibrosis)
- presence of cytotoxic substance
- collagen-vascular diseases (such as lupus erythematosus)
- disease of the liver or spleen
- radiation exposure
High numbers of WBCs (leukocytosis) may indicate: 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
- over hydration
- rheumatoid arthritis
High hematocrit may indicate: Low hemoglobin values may indicate: - anemia (various types)
- blood loss
