1. A method comprising:
inserting a lower member of a screening device into a first barrel of a first pre-filled syringe, the lower member being coupled to an upper member of the screening device and being shaped or sized to be received through syringe barrels of a plurality of pre-filled syringes for determination of a stopper position within the syringe barrels, wherein at least a portion of the lower member extends from a bottom surface of the upper member, and wherein the lower member comprises a proximal end including a flanged top configured to rest upon a top surface of the upper member prior to insertion into the syringe barrels of the plurality of pre-filled syringes;
advancing the screening device into the first pre-filled syringe until the upper member contacts a first top of the first pre-filled syringe; and
identifying the first pre-filled syringe as failing inspection in response to the proximal end of the flanged top of the lower member moving beyond a predetermined distance from the top surface of the upper member.
