what kind of test can be done to see if your blood is infected
The American Red Cross performs laboratory tests for multiple infectious disease markers on every unit of donated blood. Tests are upgraded or replaced with more sensitive technologies as these become available. These tests include: 1  Anti-Trypanosoma cruzi. 2  Hepatitis B virus (HBV). 3  Hepatitis C virus (HCV 3.0). 4  Human Immunodeficiency viruses, Types 1 and 2 (HIV 1,2). 5  Human T-Lymphotropic virus (HTLV-I/II). 6  Syphilis (Treponema pallidum).
