Blood is a substance circulating through our bodies which is crucial to life! It is made up of different blood cells. These blood cells are grouped into 3 categories: Platelets, White blood cells, and Red blood cells. Each of these cells have a unique role.

Red blood cells carry oxygen; white blood cells (which have different subtypes) assist in fighting infection, and Platelets help form clots which are important to stop bleeding in wound healing. All these blood cells are held in the fluid part of blood, called plasma.

What does blood do?

Blood plays a very important role in the transport of critical components in our body like electrolytes, vitamins, hormones, and oxygen to organs; it also has the very important function of transporting substances like carbon dioxide, and other by-products, thereby assisting in the excretion of these substances.

A complete blood count that reveals abnormal increases or declines in cell counts may point to an underlying medical problem that necessitates additional testing.

Example of test

What we learn?

Red blood cell Red blood cell count, Haemoglobin, Red cell distribution width From the test linked to red blood cells, we learn about the size shape, oxygen carrying ability of the red blood cells, and total number of red blood cells in circulation.
White cell count White cell count, differential count This test allows us to see how many white cells are in circulation and of the cells in circulation how many of each type of different white cell is present.
Platelets Platelet count, mean platelet volume Tells us how many platelets are in circulation, and what the average size of these cells are.

A qualified clinical professional will look at these results in relation to other, medical information of a patient before a conclusion is drawn.
