does this mean hiv blood does get cleaned and then used?

Scientists at NYBC were pioneers in the field of virus inactivation, developing a solvent/detergent process to eliminate dangerous viruses from plasma and plasma products, such as the clotting factor used by hemophiliacs. The solvent/detergent process destroys the coat of certain viruses - including HIV and hepatitis B and C viruses - inactivating the viruses without harming the fragile blood proteins in plasma. Every pint of blood collected is screened for markers of a variety of transfusion-transmissible diseases (HIV, Hepatitis B, Hepatitis C, HTLV-1/2 and syphilis) using serological as well as molecular (Nucleic Acid Amplification Testing) methods. Products that test positive for any of these markers are not released for transfusion. We also perform additional, confirmatory tests on donors whose screening results are positive in order to provide these individuals with relevant medical information and to provide the basis for notification of donors of their eligibility for future blood donations

Thanks for your post.

No this does not mean that blood that tests positive for HIV is used for transfusion. It states that any blood that screens positive for infectious viruses including HIV is not used for transfusion. The treatments for inactivation are there as a backup since there may be a very very small chance that infection that is very early may test negative on screening. This risk is even smaller because the blood is screened not just for antibody but for genetic evidence of the virus which is much more sensitive.
