Abstract: A syringe measurement marking system for use with a syringe that includes a barrel and a plunger is marked with patient-based numerical measuring indicia on the plunger. The patient-based numerical measuring indicia is non-volumetric in nature and instead indicates patient dosing criteria such as weight, age, height, blood sugar level, or any other patient criteria by which dosing is determined. The plunger may contain more than one set of patient-based numerical measuring indicia, such as one set for adults or one set for pediatrics, or one set for a first dose of a medication and one set for a second dose, or one set based on weight in pounds and one set based on weight in kilograms. The syringe barrel will contain one or more measurement lines.
