During the test
Bilirubin testing is done using a blood sample. Usually, the blood is drawn through a small needle inserted into a vein in the bend of your arm. The needle is attached to a small tube, in which your blood is collected.
You may feel a quick pain as the needle is inserted into your arm and experience some short-term discomfort at the site after the needle is removed. Blood for bilirubin testing in newborns is usually obtained using a sharp lance to break the skin of the heel (heel stick). There may be slight bruising at the puncture site afterward.
Your blood will be sent to a laboratory for analysis. You can usually return to normal activities immediately.
