_____
=> we know that blood runs all over the body through arteries, veins and capillaries. It takes with it whatever comes along the way.
=> for example if a bacteria enters our body, it will find suitable contidition to grow. Some the group of bacteria will be carried along the blood.
=> the bacteria uses up some of the important nutrients, minerals, proteins etc in blood because of which the level of these important biomolecules decreases. Moreover, the bacteria can produce toxins as a result of excretion which are not found in humans.
=> by comparing the their levels with normal blood sample,
we can actually get to know about the type of bacteria and the disease it is causing.
note: I am not talking about just bacteria but other pathogens as well.
