2. WHAT IS COMPLETE BLOOD COUNT?
A complete blood count (CBC) is a test that
measures the cells that make up your blood:
red blood cells, white blood cells, platelets &
other components.

3. WHY COMPLETE BLOOD COUNT TEST IS
RECOMMENDED?
Your doctor may order a CBC as part of a routine check-up or
to:
• Check for anemia
• See if you have another health issue or to explain
symptoms like weakness, fever, bruising, or feeling tired
• Keep an eye on a blood condition you already have
• See how medications or treatments
like chemotherapy are affecting your blood

4. What kinds of disorders can be detected with a
complete blood count?
Abnormal CBC results help to diagnose:
Infections
Inflammation
Cancer
Leukemia
Autoimmune conditions (diseases in which the body's immune system attacks the
body)
Bone marrow failure
Abnormal development of bone marrow
Anemia
Dehydration, fluid loss
Vitamin and mineral deficiencies
Thalassemia (a blood disorder in which the production of red blood cells is
abnormal)
Effects of chemotherapy
Effects of certain antibiotics
Effects of a number of medications in long-term or even short-term use

5. How Is a CBC Done?
It’s pretty simple and takes just a few
minutes. A nurse or lab tech will take a
sample of blood by inserting a needle into a
vein in your arm. She’ll send it to the lab for
review. You can leave and get right back to
your normal routine.

7. White blood cells (WBCs).
These help to fight infections.
Low Level of WBC indicated Inflammation
or Infection
High Level of WBC indicated risk of
Infection
The normal range is 4,500 to 10,000 cells
per microliter

8. Red blood cell count, hemoglobin and hematocrit.
They help in Transport of Oxygen and Carbon di oxide
If the measures in these three areas are lower than
normal, you have anemia. Anemia causes fatigue and
weakness.
A red blood cell count that's higher than normal
(erythrocytosis), or high hemoglobin or hematocrit levels,
could point to an underlying medical condition, such as
polycythemia vera or heart disease.

9. Platelet count
They help in clotting of blood
A platelet count that's lower than normal
(thrombocytopenia) or higher than normal
(thrombocytosis)
If your platelet count is outside the normal
range, you'll likely need additional tests to
diagnose the cause.
