I’D NEVER REALLY SEEN my child bleed before, but there I was, locked in a chair, and hugging him tightly with both arms as two lab technicians drew a tiny amount of blood from his arm.
Despite my efforts to hold him still, when the needle drove home he jerked his arm just enough to shut off the flow. One of the technicians went to the phone to find out if the tiny amount of blood would be enough to detect heavy metals.
