People with AIDS are not allowed to donate blood. One of the most important ways of spreading AIDS is through blood transmission, that is, blood containing the AIDS virus enters the body of others and causes them to be infected. At present, China’s blood donation test is very strict, AIDS patients will be screened out, such a group of people to donate blood is also unqualified, donated blood will also be discarded or do relevant processing. Therefore, high-risk groups are not recommended to donate blood in order to test for HIV, but can consider donating blood after the window period when the HIV antibody test is negative.
