We added a statement to our Educational Materials that donors must read: What happens after your donation: To protect patients, your blood is tested for hepatitis B and C, HIV, certain other viruses, and syphilis. If your blood tests positive it will not be given to a patient. You will be notified about test results that may disqualify you from donating in the future. There are some circumstances in which we cannot perform these tests (such as when we do not collect enough blood or the blood tubes are broken). Please do not donate to get tested for HIV, hepatitis, or any other infections! I agree with BC that gauze should be used, but never pressed down upon.
