A complete blood count test measures several
components and features of your blood,
Red blood cells, which carry oxygen
White blood cells, which fight infection
Hemoglobin, the oxygen-carrying protein in red
Hematocrit, the proportion of red blood cells to the
fluid component, or plasma, in your blood
Platelets, which help with blood clotting
Abnormal increases or decreases in cell counts
as revealed in a complete blood count may
indicate that you have an underlying medical
condition that calls for further evaluation.
Carry oxygen from the lungs to the rest of
the body, and carbon dioxide back to the
Low = Anemia
High = Polycythemia
Clinical Presentation would look like….
A hemoglobin test measures the amount of
hemoglobin in your blood.
Hemoglobin is a protein in your red blood cells
that carries oxygen to your body's organs and
tissues and transports carbon dioxide from your
organs and tissues back to your lungs.
If a hemoglobin test reveals that your
hemoglobin level is lower than normal, it means
you have a low red blood cell count (anemia).
Anemia can have many different causes,
including vitamin deficiencies, bleeding and
MCV- mean corpuscular volume
MCH- mean corpuscular hemoglobin
MCHC- mean corpuscular hemoglobin
Help diagnose specific types of anemia
White blood cells help fight infections. They
are also called leukocytes. There are five
major types of white blood cells which give
more detailed information about an infection.
Lymphocytes (T cells and B cells)
Clinical presentation would look like….
Hematocrit is a blood test that measures the
percentage of the volume of whole blood that
is made up of red blood cells. This
measurement depends on the number of red
blood cells and the size of red blood cells.
Normal results vary, but in general are as
Male: 40.7 - 50.3%
Female: 36.1 - 44.3%
Clinical presentation would look like…
A platelet count is a test to measure how many
platelets you have in your blood. Platelets help the
blood clot. They are smaller than red or white blood
◦ 150,000 - 400,000 platelets per microliter (mcL).
A lower-than-normal number of platelets is called
thrombocytopenia, and is seen in:
Disseminated intravascular coagulation (DIC)
Idiopathic thrombocytopenic purpura (ITP)
