Probably not a great: deal. This reflects poor phlebotomy technique (e.g double wall puncture, etc.) along with not holding pressure (single finger tip) on the location(s) of the vein(s) puncture & elevating site far above heart, after blood sample was collected. The opening in vein(s) wall(s) at that location allowed continued bleeding from the punctured vein such that accumulated blood became apparent under the skin.
