A whole blood sampling kit for obtaining blood samples from a central line. The system is comprised of three syringes, a 4-way stopcock body, and a needle or blunt cannula access devise. The three syringes are a 1 cc heparinized syringe for blood sampling, an empty 3 cc blood and infusing fluid aspirating syringe, and a 3 cc flush filled syringe. The syringes are attached to three female ports on the top of the kit's stopcock. A lever on the kit's stopcock points to the female port and syringe it is on to. A needle or blunt cannula is attached to the male adapter on the bottom of the kit's stopcock. The access device connected to the male adapter has a locking system with a matching sample site. The whole kit, via the needle or blunt cannula, attaches to a central line's sample site for withdrawing blood.
