Like "I thought I was one of the rar ones. Many times I have had to try several times before I can find blood. Other times I hit a gusher. I'm on a low dose aspirin regiment. I also have given lab tech's a fit trying to draw blood. The veins are easy to se before they set up for drawing the sample. Then vanishes. I had one tech decide I was doing it intentially, and tried finding the vein 21 times befor giving up. My supervisor sent be back to the hospital to check why I liiked like a spastic junkie. I was sent under guard. Now after 3 tries I recommend asking for a 2nd tech. Guardian stone"
