It is not possible to contract HIV, the virus that causes AIDS, by donating blood. Each needle used in the procedure is sterile and is disposed of after a single use. People in good health who weigh at least 110 pounds can donate a unit of blood as often as every eight weeks. An average healthy person will be eligible to give blood more than 330 times in his or her lifetime. There are many places where donation can be made.
Bloodmobiles travel to high schools, colleges, churches, and other community organizations.
You can also donate at the local Blood Donor Center . A single unit of blood donated by one person may be used to help several people. The blood donation process takes approximately one hour and includes a mini-physical to check your blood pressure, pulse, temperature and iron level. The American Red Cross has been operating its blood services program for the past 50 years.
