Normal Blood Values

The values for blood may vary in relationship to the altitude of your geographic location. Check with your Hematology Department if the normal values do not appear on your hematology report forms. The following values are for sea level.

Hematocrit - Men: 45% (38-51%)
Women: 40% (36-47%)

Hemoglobin - Men:                14-17 gm.%
                  Women:            12-16 gm. %
                  Children:           12-14 gm. %

Blood Counts Per cu. Mm Percent

Erythrocytes (RBC)

Men 5.0 (4.5-6.0) million
Women 4.5 (4.3-5.5) million

Reticulocytes 1.0%

Differential White Count

Leukocytes, total (WBC) 5,000-10,000 100%

Lymphocytes                          1,000-4,000                  20-40%
Segmented neutrophils             2,500-6,000                  40-60%
Band neutrophils                     0-500                           0-5%
Juvenile neutrophils                  0-100                           0-1%
Myelocytes                             0                                 0%
Eosinophils                             50-300                          1-3%
Basophils                                0-100                           0-1%
Monocytes                             200-800                        4-8%

Platelets 200,000-500,000

Certain types of disease associated with the abnormality of blood cells are:

Anemia                       - Deficiency in erythrocytes or hemoglobin
Aplastic anemia            - A form of anemia in which there is a lack of                                    formation of blood cell elements in the bone marrow
Leukemia                     - A progressive, malignant disease of the blood and                                    blood-forming organs characterized by uncontrolled                                    proliferation and development of leukocytes. It is                                    diagnosed by microscopic detection of abnormal                                    cells in the blood and bone                                    marrow.
Leukocytosis               - An increase in the number of leukocytes in the                                   blood
Leukopenia                  - Reduction in the number of leukocytes in the blood
Polycythemia               - Excessive number of erythrocytes
Thrombocytopenia        - Decrease in the number of blood platelets

Therefore, you can see that the hematology report contains information which the tumor registrar must abstract for leukemias and polycythemia vera.
