If while getting a blood test the pillow on which you put your arm had stains it can get aids if touched blood?

There is no risk of acquiring HIV from touching a pillow that may have been stained with blood. HIV is transmitted through contact with infected blood, semen, vaginal fluids, or rectal fluids. It is not transmitted through casual contact such as touching a surface that may have been contaminated with blood.

Additionally, the risk of acquiring HIV from a blood test is extremely low due to the stringent infection control measures that are followed in healthcare settings. These measures include the use of sterile needles and single-use equipment, as well as thorough disinfection and sterilization of surfaces.
