Current FDA and /or AABB guidelines require that every volunteer blood donation (allogeneic and autologous) be screened for the following:
ABO, Rh Typing
Unexpected antibody screen (immunohematologic antibodies)
Hepatitis B surface antigen
Hepatitis B core antibodies
Hepatitis C antibodies
Serologic test for Syphilis
HIV-I/II antibodies
Human T-cell lymphotrophic virus antibodies
HIV-I Nucleic Acid Test (PCR)
HCV Nucleic Acid Test (PCR)
West Nile Virus Nucleic Acid Test (PCR)
Bacterial Screening of Platelet components
Additional tests may be preformed at the discretion of the collection facility, such as Cytomegalovirus (CMV) Antibody screening, Hepatitis B Nucleic Acid Testing (PCR) and T. Cruzi antibodies (Chagas' Disease).
If any test is repeat reactive, it must be further tested using a licensed confirmatory test, if one exists. FDA guidelines also require that all blood collection facilities notify the donor of any unexpected screening test results within eight weeks of donation. However, most will notify within 4 weeks, usually by USPS 1st Class mail (or certified/restricted delivery if specified).
donor blood is screened for Infectious Diseases, such as hepatitis, AIDS, and syphilis, by testing for specific markers of these diseases that will appear in the blood of those infected.
One of the test performed on donated blood is the APA test which is used find out if the blood is clean and healthy
HIV. Though, this is to help protect the recipient, and donating blood should not be done to get an HIV test.
Ideally, someone with a blood type O should receive a blood transfusion from someone who also has the same blood type. One can have their blood type tested by donating blood.

Blood is purified when it enters a nephron through the artiole, impurities are filtered out and emptied into the collecting duct. The purified blood exits the nephron through the venule. Hope it helps ;)
