A Complete Blood Count (CBC) test is done to get information on various kinds of blood cells, such as red blood cells, white blood cells, and platelets. A CBC test helps the doctor detect any bruising, fatigue, or weakness in the body. Other health conditions such as anemia, infections can also be detected with the help of a CBC test.

Red blood cells
White blood cells

Check your red blood cells count with the help of a CBC Test!
What is included in a CBC test?
A Complete Blood Count test usually includes the following:
Red blood cell (RBC) count: Red blood cells are also known as erythrocytes and the main function of red blood cells is to carry oxygen from the lungs to the entire body. It also carries back carbon dioxide to the lungs. If the RBC count is low, it is known as anemia, the body will not receive enough oxygen. There is also a condition called polycythemia where the red blood cells can get clumped together and block the capillaries.
White blood cell (WBC) count:White blood cells are also known as leukocytes. They protect our bodies against infection. When a foreign particle enters our body, the WBC fights against the foreign particle. The overall count of white blood cells is less than red blood cells. Whenever there is an infection, the count of white blood cells increases. White blood cells are also used for detecting infection.
Platelet count:Platelets are also known as thrombocytes and these are the smallest type of blood cell. They are important in blood clotting. When bleeding starts, platelets swell and clump together to form a sticky plug that will stop the bleeding. If the platelet count is low in the body, it becomes difficult to stop bleeding. If the platelet count is high in the body, it may form a clump and block a blood vessel. There is also a condition known as atherosclerosis where the platelets may be involved in the blocking of the arteries.
Hemoglobin:The red blood cell is filled with hemoglobin molecules. It is responsible for the color red and it also carries oxygen. Through a hemoglobin test, the amount of hemoglobin is measured and the ability of the body to carry oxygen throughout the body.
CBC Test procedure
A complete blood count test (CBC) is carried out by a lab technician.
The place from where the blood sample is collected is first cleaned.
An elastic band is placed above the cleaned area so that the veins swell with blood.

The blood sample is then pulled into a syringe.
After collecting the blood sample, the needle and the elastic band is removed.
