Giving blood to yourself for an operation is the best way to avoid diseases.
If you're having elective surgery, talk to your doctor about donating blood -- to yourself.
"Blood banks take great care in testing donors' blood, but if patients can give their own blood, it is definitely the best way to avoid diseases, such as hepatitis B and HIV," says Joseph C. McCarthy, M.D., an orthopaedic surgeon at New England Baptist Hospital in Boston.
