The white blood cell (WBC) count indicates the number of white blood cells in a sample of blood. This count provides a clue to the presence of illness.White blood cells are made in the bone marrow and protect the body against infection and aid in the immune response.his count provides a clue to the presence of illness. White blood cells are made in the bone marrow and protect the body against infection and aid in the immune response.
A high WBC indicates infection, inflammation and some types of cancer or leukemia. If the WBC is low, it can point to bone marrow abnormalities, viral infections or overwhelming infections or blood poisoning. A normal range for the white blood cell count is between 5.5 and 19.5.White blood cells are measured in thousands per cubic milliliter (K/uL), which means it's normal to have between 5,500 and 19,500 white blood cells per cubic milliliter of blood.uch counts may signal bleeding or excessive destruction of platelets caused by immune disease or parasites. A normal platelet level is between 200 and 500. Platelets are measured in thousands per cubic millimeter, meaning a normal cubic millimeter (m/uL) of blood should have between 200,000 to 500,000 platelets.
