Safety of the blood supply
To ensure maximum safety and effectiveness, Memorial Blood Centers prepares and tests all blood donations. Every blood product must pass at least 12 tests before it is deemed safe for transfusion. Donations with unacceptable test results are promptly discarded and destroyed.
Tests routinely performed on every donation include:
Blood is tested to determine the ABO group (A, B, O, or AB) and Rh factor (positive or negative).
All donations are tested to determine if their plasma contains any antibodies to various red blood cell antigens.
Tests for Infectious Diseases
Testing for infectious diseases is one of the most important ways of ensuring the safety of all blood products. The following tests are performed on each blood product before it is available for transfusion:
- HIV 1 & 2
- Hepatitis B
- Hepatitis C
- HTLV (Human T-Lymphotrophic Virus) Type I/II
- Syphilis Antibody
- West Nile Virus
- Antibody for Chagas' Disease
- Zika Virus

Infectious disease testing is performed for the safety of the blood supply. Please do not donate blood as a means of screening for any infection or condition.
