Normal CBC Values


Knowing the CBC normal values is important. A complete blood count (CBC) is a basic diagnostic test performed in order to determine the amount of white blood cells, red blood cells, platelet, hematocrit and hemoglobin in the blood. Each of these components play vital roles for our health, and any deviation from the CBC normal values would mean that something is wrong in the body. Values that do not conform to the standard range are indicative of the presence of a health problem, ranging from a mild infection to a serious disease.

Why is it important to have CBC normal values?

CBC serves a significant role in the healthcare of a patient. It helps in the confirmation of the existence of an ailment and in determining the real cause of a disease.  It is also used by the doctor for regular checkups in order to evaluate the present health condition of a person, as well as monitor the progress of a patient who has been under treatment. Needless to say, having CBC normal values is one of the indicators that a person is in the pink of health.

What are the CBC normal values?

 Each of the components of blood has its own normal range.

  • White Blood Cells

White blood cells (WBC) are part of the natural immune defense system that helps protect the body and fight off any foreign matter that tries to enter the system. The WBC is measured in thousands per cubic milliliter (K/uL) or converted to cells per cubic milliliter (cmm). The WBC count is also referred to as leukocyte count. The CBC normal values for WBC range from 4.3 K/uL to 10 K/uL or 4300 cmm to 10 000 cmm. Any values lower than the normal means that the immune system is weak so the individual is prone to infection. A common case wherein the WBC drops lower than the normal range is when the person has cancer. Meanwhile, if the WBC count exceeds the normal range, it would indicate that the person has an infection. This is because the leukocytes increase in number to fight off foreign substance that has entered the system.

  • Red Blood Cells

The red blood cells (RBC) function to carry oxygen and distribute it throughout the body in order for the body parts to function properly.  At the same time they help eliminate the waste products from the tissues. The RBC is measured in millions per cubic milliliter (M/uL). The CBC normal values for RBC count are between 4.2 and 5.9 M/uL. If the RBC count is lower than the normal values, the person might have anemia.

Below are some components of the RBC count that aid in the proper diagnosis of a person’s health condition.

  • Hematocrit – This signifies the total amount of the red blood cells relative to the whole blood volume (percentage of RBC). The CBC normal values for hematocrit count vary with the gender. For males, the normal values range between 45% and 52%; whereas for females, the normal range is 37% to 48%. If the hematocrit value is higher than normal and if it comes with a low platelet count, the patient most probably has dengue fever.
  • Hemoglobin – Hemoglobin is a molecular part of the red blood cells that is responsible for the color of the blood. Aside from that, it also helps in the transport of oxygen to the different parts of the body. Hemoglobin is measured in grams per deciliter (g/dL). CBC normal values for hemoglobin also vary with the sexes. For men, the normal hemoglobin count ranges between 13 and 18 g/dL. While for women, the normal hemoglobin count ranges from 12-16 g/dL.
  • Platelets

Platelets are responsible for blood clotting to prevent excessive bleeding. They are measured in thousands in cubic millimeter (m/uL). The CBC normal values for platelets would range from 150 – 400 K/uL or 150 000 to 400 000 cmm. If the platelet count is lower than the normal range, there is a probability of having thrombocytopenia. This is a condition wherein you would bruise easily, your gums would bleed easily, and you are in danger for excessive bleeding in case you get into an accident that would open up a wound. A low platelet count could also mean dengue fever if this is paired up with a high hematocrit.

The CBC normal values can be achieved easily with healthy living being the key. Remember that what we do to our body, our body would give back to us. If we take care of it, then it would take care of us. However, if the departure from the normal values of the complete blood count is due to an unfortunate event like an accident or a genetically acquired disease, the best thing to do is to see a doctor, seek advice on how to correct it, and have regular checkups and laboratory tests to ensure that the complete blood count is maintained at normal levels. It would also help to eat the right food, have regular exercises and avoid excessive stresses.
