How It Feels
Blood sample from a heel stick
The baby may feel a brief sting or a pinch when the lancet pricks
the skin. While the blood is being collected, there is very little or no
discomfort.
Blood sample from a vein
You may feel nothing at all from the needle puncture, or you may
feel a brief sting or pinch as the needle goes through the skin. Some people
feel a stinging pain while the needle is in the vein. However, many people do
not feel any pain, or have only minor discomfort, once the needle is positioned
in the vein. The amount of pain you feel depends on the skill of the health
professional drawing the blood, the condition of your veins, and your
sensitivity to pain.
The collection of DNA from saliva, urine, or semen does not cause
discomfort.
