Complete Blood Count (CBC) - $20.00
CBC THIS WILL AN ADDITIONAL TUBE - The CBC is one of the most commonly ordered blood screenings and is
used to present a general picture of a person’s overall health.
It also is used to diagnose disease when people are “not feeling
well.” It is also used to monitor treatment of many diseases, including
anemia and leukemia. In the CBC test, the different types of cells in
the blood are counted and examined by a machine.
White Blood Cell Count - White blood cells protect the body against infection. If an infection
develops, white blood cells attack and destroy the bacteria, virus, or
other organism causing it. White blood cells are bigger than red blood
cells and normally fewer in number. When a person has a bacterial infection,
the number of white cells can increase dramatically. The number of white
blood cells is sometimes used to identify an infection or monitor the
body's response to cancer treatment.
Red Blood Cell Count - Red blood cells carry oxygen from the lungs to the rest of the body.
They also carry carbon dioxide back to the lungs so it can be exhaled.
If the RBC count is low (anemia), the body may not be getting the oxygen
it needs. If the count is too high (a condition called polycythemia vera),
there is a risk that the red blood cells will clump together and block
tiny blood vessels (capillaries).
Hematocrit Value - This test measures the amount of space (volume) red blood cells occupy
in the blood. The value is given as a percentage of red blood cells in
a volume of blood. For example, a hematocrit of 38 means that 38% of the
blood's volume is composed of red cells.
Hemoglobin Concentration - Hemoglobin is the major substance in a red blood cells. It carries oxygen
and gives the blood cell its red color. The hemoglobin test measures the
amount of hemoglobin in blood and is a good indication of the blood's
ability to carry oxygen throughout the body.
Red Blood Cell Indices - There are three red blood cell indices: mean corpuscular volume (MCV),
mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration
(MCHC). They are measured by a machine and their values are determined
from other measurements noted during a CBC. The MCV shows the size of
the red blood cells. The MCH value is the amount of hemoglobin in an average
red blood cell. The MCHC measures the concentration of hemoglobin in an
average red blood cell. These numbers help in the diagnosis of different
types of anemia. Red cell distribution width (RDW) can also be measured
which indicates different sizes of red blood cells are present.
Platelet (thrombocyte) count - Platelets are the smallest type of blood cell. They play a major role
in blood clotting. When bleeding occurs, the platelets swell, clump together,
and form a sticky plug that helps stop the bleeding. If there are too
few platelets, uncontrolled bleeding may be a problem. If there are too
many platelets, there is a risk of a blood clot forming in a blood vessel.
Also, platelets may be involved in hardening of the arteries (atherosclerosis).
White Blood Count Differential - The major types of white blood cells are neutrophils, lymphocytes, monocytes,
eosinophils, and basophils. Immature neutrophils, called band neutrophils,
are also included and counted as part of this test. Each type of cell
plays a different role in protecting the body. The numbers of each one
of these types of white blood cells give important information about the
immune system. An increase or decrease in the numbers of the different
types of white blood cells can help identify infection, an allergic or
toxic reaction to certain medications or chemicals, and many conditions,
such as leukemia.
