Why is a two-step cleansing process used during blood donation?

A two-step cleansing process is utilized during blood donation primarily to reduce the risk of infection. This procedure involves thoroughly cleaning the skin at the site of the blood draw before the needle is inserted. The initial step usually involves an antiseptic solution, such as an alcohol swab, which is used to remove surface contaminants. The second step often involves a different antiseptic, such as iodine-based solutions, which further disinfect the area by targeting bacteria and other pathogens that may not have been removed during the first step. By employing this rigorous cleansing protocol, healthcare professionals aim to minimize the potential for introducing infections into the bloodstream, thereby ensuring the safety for both the donor and the recipient of the blood.

While other options may seem relevant to the donation process, they do not directly address the primary concern of infection prevention, which is critical in medical procedures involving blood. Understanding the importance of infection control is vital for those in the phlebotomy field.
