title: Consequence of syringe-plunger contamination.
abstract: Any microorganisms, which might be placed onto the sides of a syringe plunger by finger contact while withdrawing the plunger, can be transferred to the inside of the barrel and enter the fluid pathway if the plunger is drawn in and out several times. Tests are described to show which of several brands of syringes allow this contamination to occur.
