1 One out of every 10 people entering a hospital needs blood. 2  Just one pint of donated blood can help save as many as three people's lives. 3  The average adult has 10 pints of blood in his or her body.
This is the most common type of donation, during which approximately a pint of 'whole blood' is given. The blood is separated into transfusable components â red cells, plasma, platelets and/or cryoprecipitated AHF. This type of blood donation usually takes about an hour, though the actual donation takes about 8-10 minutes. You are eligible to donate 'whole blood' every 56 days.
