A content-coded syringe (2) for medical use includes a generally tubular body (4) and a plunger (6) slidably disposed in the body (4). A content code (70) corresponding to a syringe content type to be introduced into the syringe (2) is permanently and directly formed on the body (4) or the plunger (6) or both. It is selected from a set of content codes used on other syringes of like design that are adapted to receive other syringe content types. A set (80) of such syringes with unique content codes can thus be used in a medical procedure to uniquely identify the syringe contents and thereby minimize syringe misidentification. (FIG.1)
