RBC - Red blood cells
(erythrocytes - eh-REETH-ro-site) Ref. Range 4.20 - 5.70
Cells that deliver oxygen throughout the body and make
blood look red.
A low RBC can indicate
anemia, which
can lead to fatigue.
HGB - Hemoglobin (HE-muh-glow-bin)
Ref. Range 13.2 - 16.9
Hemoglobin is a protein used by red blood cells to distribute oxygen
to other tissues and cells in the body. Low levels indicate anemia.
HCT - Hematocrit (he-MAH-to-crit) Ref. Range 38.5 - 49.0%
Percent of your blood that is occupied by red blood cells. Good
indicator of anemia.
MCV - Mean Corpuscular Volume
Ref. Range 80 - 97
Measures the size of red blood cells. Larger or smaller than normal
red blood cells may indicate anemia.
MCH - Mean Corpuscular Hemoglobin
Ref. Range 27.5 - 33.5
Measures the amount of hemoglobin in red blood cells. Both hemoglobin
and hematocrit are used to calculate this number. Low levels indicate anemia.
MCHC - Mean Corpuscular Hemoglobin
Concentration Ref. Range 32.0 - 36.0%
Measures the amount of hemoglobin in red blood cells. Both HGB and HCT
are used to calculate this number. Low level indicates anemia.
RDW - Red Cell Distribution Width Ref.
Range 11.0 - 15.0
Measures the range of sizes of red blood cells in a blood sample. RDW
results are often used together with MCV results to determine possible
cause of anemia when anemia is indicated by other test results.
Platelets Count Ref.
Range 140,000 - 390,000 (mm3)
Platelets are cells produced by the bone marrow to help your blood
clot in order to stop bleeding from injury. Decreased platelet count is
called thrombocytopenia.
MPV - Mean Platelet Volume
Ref. Range 7.5 - 11.5
Measures the average volume (size) of your platelets.
Higher-than-normal MPV is associated with an increased risk of heart
attacks and stroke.
WBC - White Blood Cell
(leukocytes) Ref. Range 3,900 - 10,000
(mm3)
Measures the amount of white blood cells. These immune cells
form in the bone marrow to help fight infection. High
levels may indicate infection. Low levels may result from treatment or
disease.
Differential - Information on specific types
of leukocytes
Neutrophils
Ref. Range between 38% and 80% of the WBC
Most common granulocyte (55-70% of all leukocytes are neutrophils)
Attracted to sites of injury and infection. Percentage is often
increased during a bacterial infection. A low number (neutropenia)
increases risk of bacterial infection. Multiplying the
percentage of neutrophils by the total number of white blood cells
will give the "absolute" number of these types of cells.
Neutrophil Count (Absolute) Ref.
Range 1.8 - 7 (x1-3uL)
Lymphocytes%
Ref. Range between 15% and 40%
of the WBC
Include T-cells, B-cells, and natural killer (NK) cells.
Viral
infections may increase their number.
Lymphocyte Count (Absolute)
Ref.
Range 1000 - 3500
Multiply the Lymphocytes% above by the total number
WBC
Monocytes
Ref. Range 0.0 - 13.0
Monocytes are a type of phagocyte. These mature into macrophages,
important germ eating cells. A low number can put you at a higher
risk of getting sick from an infection, particularly those caused by
bacteria.
Monocyte Count
(Absolute)
Ref. Range 40 - 900
Multiply Monocytes% by the WBC
Eosinophils%
Ref. Range 0.0 - 8.0
A type of phagocyte that produces the
anti-inflammatory protein histamine.
A high number indicates
allergies or parasitic infections.
Eosinophil Count
(Absolute)
Ref. Range 30 - 600
Multiply Eosinophils% by the WBC
Basophils%
Ref. Range 0.0 - 2.0
Control inflammation and damage of tissues in the body.
Basophil Count (Absolute)
Ref. Range 40 - 900
Multiply Basophils% by the WBC
Your
doctor will sometimes schedule a CBC blood test to monitor your
health, watch for indications of disease progression, response
to - and side effects of - treatment.
