A pencil-grip fine needle aspiration syringe holder for accurately placing a needle into a region using a single hand disposed close to the needle tip in a position of natural function, useable with a standard syringe. A body is provided for receiving a syringe barrel, and a slide is movably mounted to the body for engaging a syringe handle, for movement between a withdrawal position where a syringe plunger is in a compact position and a released position where the plunger is in an extended position. A finger engaging member is fixed to the body for grasping the holder in a pencil-grip manner, and a biasing member is coupled between the body and the slide for urging the slide toward the released position and the plunger toward the extended position. A catch is provided for restraining the slide in the withdrawal position and plunger in the compact position, along with a release for releasing the catch to allow the slide to move away from the withdrawal position and towards the released position, decreasing pressure within the syringe. A limit member is situated for limiting movement of the slide and the plunger toward the extended position. An adjustable regulating member is coupled to the limit member for adjusting the position of the limit member relative to the body.
