How It Is Done
Blood sample from a heel stick
For a heel stick
blood sample, several drops of blood are collected from the heel of your baby.
The skin of the heel is first cleaned with alcohol and then punctured with a
small sterile lancet. Several drops of blood are collected in a small tube.
When enough blood has been collected, a gauze pad or cotton ball is placed over
the puncture site. Pressure is maintained on the puncture site briefly, and
then a small bandage is usually applied.
Instead of the standard
heel stick, some hospitals may use a device called a transcutaneous bilirubin
meter to check a newborn's bilirubin level. This small handheld device measures
bilirubin levels when it is placed gently against the skin. With this device,
there may be no need to puncture the baby's skin. This is a screening test, and
a blood sample will be needed if your baby's bilirubin level is high.
Blood sample from a vein
