“Haematology Test” The Importance of Monitoring Blood Count Test

The blood is a life sustaining body tissue in the form of a liquid. It performs very

important functions in the human body such as transportation of substances

including nutrients, oxygen, and hormones from one part of the body to the

other. Additionally, it also offers protection against diseases, and regulates body

temperature. Haematology is a branch of medicine that studies the composition

of blood and blood related diseases. A haematological test is a commonly used

diagnostic tool to detect various underlying medical conditions.

The most frequently used haematology test is the complete blood count (CBC).

In a CBC test, the number blood components such as red blood cells, white blood

cells, and platelets are measured. If the count of these blood components are

found to be abnormal, it is an indication of anomalies if the functioning of the

body. A CBC is a very simple and effective test to diagnose various medical

conditions at an early stage. To understand how complete blood count test

works, it is important to get acquainted with the important components of blood

such as:-

RBC:-

Red blood cells, also known as erythrocytes are the components of the blood

that are responsible for delivering oxygen throughout the body. The normal

count as per Haematology RBC standards for a healthy adult is between 3.6 -

6.1 million red blood cells in a single cubic millimetre of blood. Abnormalities in

RBC counts could indicate various diseases related to heart, kidney or lung. A

Low blood count is also associated with a condition called Anaemia.

WBC:-

White blood cells, also called leukocytes, defend the body against infection.

Generally, a healthy adult has 4,000 to 11,000 white blood cells per cubic

millimetre of blood as per Haematology WBC standards. They are much fewer

in number than red blood cells, accounting for about 1 percent of your blood.

An abnormal WBC indicates that the existence of viral and bacterial infections,

and liver and spleen disorders.

Platelets: -

Platelets, also known as thrombocytes, are elements in the blood that facilitate

clotting. A normal platelet count of a healthy adult is between 150,000 and

440,000 per cubic millimetre of blood. Abnormal platelet counts could be an

indication of autoimmune diseases or cancer.
