Antisepsis

Antisepsis is the process of reducing or eliminating the presence of pathogenic microorganisms on living tissue or inanimate objects. In healthcare settings, antisepsis is commonly performed before invasive procedures or surgeries to reduce the risk of infection. Examples of antiseptic agents include alcohol-based hand sanitizers, chlorhexidine, and povidone-iodine (Betadine).

In the context of blood donation, a betadine swab is used to cleanse the skin at the venipuncture site before needle insertion. This helps to reduce the risk of introducing bacteria or other contaminants into the bloodstream during the blood collection process.
