After you have donated, your blood will be tested for syphilis, HIV (the virus that causes AIDS), hepatitis, and HTLV (human T-lymphotropic virus), which can cause a blood or nerve disease.
What disqualifies you from donating blood or plasma?
Blood and bleeding diseases or issues will often disqualify you from donating blood. If you suffer from hemophilia, Von Willebrand disease, hereditary hemochromatosis, or sickle cell disease, you are not eligible to donate blood. If you have sickle cell trait, it is still acceptable for you to donate blood.15 Jan 2021
Why would you be denied to donate plasma?
Not generally — people who take certain prescription drugs, show signs of injectable drug use, or are visibly intoxicated are not allowed to donate plasma. Ever having had viral hepatitis A, B, or C disqualifies a person from donating, as do certain chronic diseases like hemophilia or other bleeding disorders.12 Nov 2019
