glycerinated phenol saline solution

Glycerinated phenol saline solution is a diagnostic reagent and diluent typically composed of 50% glycerol, 0.9% sodium chloride, and 0.4% phenol. It is primarily utilized in clinical allergy practice as a negative control during skin prick testing (SPT) to establish a baseline for non-specific skin reactivity or dermographism, ensuring that any wheal-and-flare responses from allergen extracts are accurately interpreted. Additionally, it serves as a stabilizing diluent for preparing allergen extracts and positive controls like histamine dihydrochloride.
