Blood test

Child providing blood sample

A small sample is taken from a vein on the patient's forearm or hand. The procedure is completed by a Phlebotomist, a trained professional with experience accessing veins in young children and teens. First, the skin over the vein is cleaned with an alcohol solution (antiseptic). Then a tight band or tourniquet is wrapped around the arm, above the site, enlarging the veins below it by limiting blood flow to them. A fine needle is then smoothly and gently inserted into the vein and the tight band is taken off the arm. Blood flows from the vein through the needle and into a special vial. Once complete, the needle is removed and the puncture site is covered with a band-aid, hindering bleeding or bruising in the area.
