All blood transfused to patients undergoes mandatory checks for HIV, HBsAg, HCV, VDRL, Malaria, etc. The risk of developing an infection with an episode of blood transfusion is negligible, since the tests used for screening are very sensitive, but may miss a sample in the window phase / incubation phase. However, the risk increases according to the number of transfusions.
For you own mental satisfaction, you could undergo HIV, HBsAg and HCV testing, though it is not recommended as a routine.
