What is the process for getting a blood sample taken?

Blood samples are taken by a doctor, nurse or another healthcare professional. The process for getting a blood sample taken is as follows:

  • The healthcare professional ties a tight band called a tourniquet around the person's upper arm. This makes it easier to find a vein.
  • The skin is cleaned with a wipe to get rid of any germs before the blood test.
  • A small needle is put through the skin and into the vein. It feels like a sharp pinch that doesn't last long. The needle is attached to a tube that sucks up a small sample of blood.
  • The tourniquet is removed, the needle is removed and a bandage is put on where the needle was put through the skin.
