A sterile device consisting of a calibrated barrel (cylinder) with plunger, intended to be used to administer a precise, low-dosage injection of tuberculin and/or sensitivity test allergen to a patient subcutaneously; a non-retractable needle is included, either attached or detached (usually capped for user protection). The syringe is typically made of plastic and silicone materials and will have plunger anti-sticking properties allowing smooth plunger movement. It can be used by healthcare personnel or patients. This is a single-use device.
