"Blood is that fragile scarlet tree we carry within us"-Osbert Sitwell
When a person is voluntarily ready to donate blood, then he can be considered for blood donation. In developing countries most of the people donate blood for community purposes. In developing counties, donors usually give blood when family or friends need a transfusion. Before donating blood, the donor needs to take a relative physical examination and answer the questions related to his/her medical history to make sure that the donation is not hazardous to his/her health. The amount of blood drawn and methods vary from person to person. The instruments used for blood donation have short shelf life and should be maintained on a constant supply. Blood donation is of four types:
1. Homologous donation: Blood donation for the purpose of blood bank storage.
2. Directed donation: Donating the blood to the family members or specific individuals on need.
3. Replacement donor donation: Combination of Homologous and directed donation.
4. Autologous donation: Transfusing the donated blood to the same person at a later date.

There will be a medical checkup before the blood donation and a person is advised to take rest for 5 to 10 minutes and given some refreshment after donation. The complete process of blood donation takes minimum 30 minutes. A person is advised to take minimum 3 months gap between one donation to another to regain the normal hemoglobin count.
A sample of blood is screened for the following diseases/infections before grouping:
The donated blood is grouped and stored either as whole blood or as components like packed red blood cells, plasma or platelets. These packets are sent on demand to hospitals. Blood is composed of cells suspended in a liquid.
Suspended in the plasma are three types of cells:
1. Red cells: Carry oxygen
2. White cells: Fight against infection
3. Platelets: Stop wounds bleeding
Based on the presence of protein coat on the surface of the blood it is grouped into 5 major types like:
1. ABO grouping (Common grouping)
2. A (A protein is present)
3. B (B protein is present)
4. AB (AB protein is present)
5. O (no protein is present) Based on the Rh factor also blood grouping is done. If Rh is present, the particular blood type is called positive otherwise it is called negative.
