← 1. Blood typing/ RH typing
← Blood is often grouped according to the ABO blood typing system. This method breaks blood types down into four categories:
← Type A
← Type B
← Type AB
← Type O
← Blood typing is also done to tell whether or not you have a substance called Rh factor on the surface of your red blood cells. If you have this substance, you are considered Rh+ (positive). Those without it are considered Rh- (negative).
← This test is done to determine a person 's blood type. Health care providers need to know your blood type when you get a blood transfusion or transplant, because not all blood types are compatible with each other. For example:
← If you have type A blood, you can only receive types A and O blood.
← If you have type B blood, you can only receive types B and O blood.
← If you have type AB blood, you can receive types A, B, AB, and O blood.
← If you have type O blood, you can only receive type O blood.
← The procedure (Forward typing)
← 2. Blood smear
← When a peripheral blood sample is smeared on a slide and stained, it is known as a peripheral blood film. It allows for examination of the physical characteristics of the red cells, white cells and platelets under the microscope.
← Additionally, it helps detect parasites or abnormal cells in the blood. Thus the peripheral blood film is an important indicator of hematological and other disease.

← 3. Coagulation test
A. Bleeding Time Test
← Bleeding time is a very popular blood test that is primarily used to gauge the speed with which the blood is able to clot.
← The clotting of blood incorporates the functionality of a number of factors such as coagulation factors, platelets, as well as small vessel vasospasm.
