These appear to be the currently performed test for donated blood as posted by the Blood-Mobile folks:
"In the United States, at the time of this writing, before your donated Blood is made available for transfusion, it will be tested as follows:
ABO Typing - provides determination of Blood type: A, B, O, or AB.
Rh Factor Determination - indicates positive or negative Blood type.
Blood Group Antibodies - indicates unexpected antibodies that may be a result of prior transfusion, pregnancy or other factors.
Hepatitis B Surface Antigen - indicates a present infection (hepatitis) or carrier state of hepatitis B virus.
Antibody to Hepatitis B Core - additional test that detects a present or past infection with the hepatitis B virus.
Antibody to Hepatitis C Virus - indicates antibody to a virus that causes hepatitis C (responsible for non-A non-B hepatitis.) The mean incubation time is six to eight weeks.
Alanine Aminotransferase (ALT) - identifies a liver enzyme that, when increased, may indicate undetectable forms of hepatitis.
Antibody to HTLV - 1 and 2 - indicates the antibody to a virus that causes adult T-cell leukemia, among other things.
Antibody to HIV 1 and 2 - indicates an infection with Human Immune deficiency Virus.
Syphilis - screens for this dangerous venereal disease."
So it also appears that testing should demonstrate infection-free blood from homosexuals acceptable for use.
Here's a link to info regarding the tests that the Red Cross routinely runs on donated blood.
I did not realize that the testing was so extensive. That realization has given me pause, since the need for blood transfusions is constant and huge. But, it still seems prudent to just not use high-risk groups of people for donors.
