Needle Placement and Test Administration
With the bevel up, insert the needle intradermally. Slowly depress the plunger ensuring the syringe is stable until a wheal is produced. Discard the needle in a sharps container. Ensure the wheal measures 6-10 mm in diameter. Instruct the patient to not cover with an adhesive bandage, scratch or irritate the area. A cotton ball may be used to gently dab the area, if necessary.
