5. Result
The following are normal CBC results for adults:
Red blood cells :
Male: 4.2 - 5.4 T/l Female: 4.0 - 4.9 T/l Hemoglobin:
Male: 130 - 160 g/l Female : 125 - 142 g/l Hematocrit:
Male: 0.42 - 0.47 L/L Female: 0.37 - 0.42 L/L WBC : 4.0 - 10.0 G/l
Platelets : 150 - 450 G/l
Abnormal results :
Red blood cells, hemoglobin and hematocrit are lower than normal in the state of
anemia. Anemia causes fatigue and weakness. Anemia has many causes, including: blood loss, hemolysis, malnutrition, or disease of the bone marrow.
Higher-than-normal red blood cells (erythrocytosis), high hemoglobin or hematocrit in conditions of blood concentrates, polycythemia vera, or heart disease.
Low white blood cell count (leukopenia) is seen in many medical conditions,
such as an autoimmune disorder that destroys white blood cells, bone marrow problems or cancer. Certain medications can also cause low white blood cell counts. If the white blood cell count is higher than normal, an infection or inflammation may be present. Or, it could indicate an immune system disorder or bone marrow disease.
Elevated white blood cells can also be a reaction to medication. A platelet count that is lower than normal (thrombocytopenia) or higher than normal is usually a sign of a medical condition, or it can be a side effect of medication. If the platelet count is outside the normal range, further tests may be needed to diagnose the cause.
Abnormal results in the complete blood count test reflect many medical conditions of the body, so it is important to talk to your doctor so that you can get the necessary advice. In many cases, your doctor may refer you to a hematologist, who has extensive experience in blood-related diseases, for further advice.
