Claim:
1. A method for assembling a syringe, the method comprising: supporting a syringe barrel that bounds a compartment extending between a loading end and an opposing dispensing end, a stopper being movably disposed with the compartment of the syringe barrel with a liquid dosage being disposed within the compartment between the stopper and the dispensing end; inserting a distal end of a plunger rod into the compartment of the syringe barrel at the loading end thereof; taking an initial digital image of the stopper within the syringe barrel either before, during or after inserting the distal end of the plunger rod into the compartment of the syringe barrel; coupling the distal end of the plunger rod to the stopper located within the compartment of the syringe barrel so that the plunger rod is secured to the stopper; taking a plurality of further digital images of the stopper within the syringe barrel during or after coupling the distal end of the plunger rod to the stopper; and comparing information determined from each of the further digital images to information determined from the initial digital image using a computer processor to determine if the stopper in each of the further digital images has moved relative to the syringe barrel.
