Selection of donor include physical and medical examinations of doner that include Age, Hemoglobin, Packed Cell Volume (Haematocrit), Weight, Blood Pressure, Temperature, Pulse, etc

Selection of donor | Blood transfusion

Most healthy individuals can donate blood without any ill effects. However, the selection of donors and proper identification of a donor is essential so that the blood collected for transfusion is safe and beneficial to the patient (recipient). Most blood donations are voluntary.

Selection of donor | Blood transfusion

Two basic principles must be kept in mind when the donor is selected:

1. The blood collection procedure should not be harmful to the donor.
2. The donor's blood should not be harmful to the recipient.

The selection of the blood donor involves a medical history and simple physical examination (pulse rate, blood pressure), and later, screening for transfusion-transmissible diseases.
