1. A disposable pricker comprising an elongate body with a lancet non-rotatably carried therein, the lancet tip normally being within the body, a spring urging the lancet in a direction to project its tip from the body, a trigger mechanism carried by the body with a portion within the body arranged to retain the lancet in a fully retracted position energizing the spring and a second portion outside the body manually actuable to release the lancet to cause the tip to have a momentary position projecting from an opening in the forward end of the body, and a cap encasing the lancet tip and having a shank traversing said opening, wherein said shank extends outwardly of said body through said opening a distance sufficient to permit said lancet to be moved against the action of said spring to said fully retracted position solely by pushing said cap further into said body through said opening, and wherein said cap is breakable free of the lancet by twisting when so retracted to leave the tip exposed within said body.
