Potentiator

In clinical terms, a potentiator is a reagent that enhances sensitization of an antigen. Potentiators are used in the clinical laboratory for performing blood banking procedures that require enhancement of Agglutination (biology) to detect the presence of antibodies or antigens in a patient's blood sample. Examples of potentiators include albumin, LISS (low ionic-strength saline) and PEG (polyethylene glycol). Potentiators are also known as enhancement reagents.
