Blood Test Part 3 – Complete Blood Count





Normal range: 4,300 to 10,800 cmm
White blood cells assists fighting infections, therefore high white blood cell count could be advantageous for identifying infections. But on the other hand it may also indicate leukemia, which can cause an increase in the number of white blood cells. But, too few white blood cells could be caused by certain medications or health disorders.

Normal range:
Neutrophils             40% to 60% of the total
Lymphocytes          20% to 40%
Monocytes              2% to 8%
Eosinophils             1% to 4%
Basophils                0.5% to 1%

This test scrutinizes the numbers, shapes, and sizes of various types of white blood cells listed above. The WBC differential count also indicates if the numbers of different cells are in proper proportion to each other. Irregularities in this test could indicate an autoimmune disorders, anemia, infection, inflammation or other health problem.

Normal range: 4.2 to 5.9 million cmm
There are millions of red blood cells in our bodies. This test scrutinizes the number of RBCs in a specific amount of blood. It assists us to determine the total number of RBCs and to provide us an idea of their lifespan, however it does not show where problems develop. In such an extent, if having other irregularities, other tests will be required.

Normal range: 45% to 52% for men; 37% to 48% for women
It is useful for diagnosing anemia, this test determines how much of the total blood volume in our body consisting of red blood cells.

Normal range: 13 to 18 g/dL for men; 12 to 16 g/dL for women
Hemoglobin contained in red blood cells makes blood bright red. Hemoglobin delivers oxygen from the lungs to our entire body. Thereafter it returns to our lungs with carbon dioxide, which we exhale. Healthy hemoglobin levels vary by gender. Low levels of hemoglobin may indicate anemia.

Normal range: 80 to 100 femtoliters
MCV test measures the average volume of red blood cells, or the average amount of space each red blood cell fills. Irregularities could signal anemia and/or chronic fatigue syndrome.

Normal range: 27 to 32 picograms
MCH test measures the average amount of hemoglobin in the typical red blood cell. Too high results could signal anemia, while too low results may indicate a nutritional deficiency.

Normal range: 28% to 36%
MCHC test informs the average concentration of hemoglobin in a specific amount of red blood cells. Here again too low results could signal anemia, while too high results may indicate a nutritional deficiency.

Normal range: 11% to 15%
With RDW/RCDW test, we obtain a view of the shape and size of red blood cells. “Width” refers to a measurement of distribution, not the size of the cells. High or low RDW results can be caused by anemia, liver disease, nutritional deficiencies and a number of health conditions.

Normal range: 150,000 to 400,000 mL
Platelets are small portions of cells involved in blood clotting. Too few or too many platelets can affect clotting in different ways. The number of platelets may also signal a health condition.

Normal range: 7.5 to 11.5 femtoliters
MPV test estimates and calculates the average size of platelets. Higher MPVs signify the platelets being larger, which could cause a person at risk for a heart attack or stroke. Lower MPVs signify smaller platelets, indicating the person being at risk for a bleeding disorder.
