Sickle Cell Test
How It Is Done
Blood sample from a vein
The health professional drawing blood will:
- Wrap an elastic band around your upper arm to stop the flow of blood. This makes the veins below the band larger so it is easier to put a needle into the vein.
- Clean the needle site with alcohol.
- Put the needle into the vein. More than one needle stick may be needed.
- Attach a tube to the needle to fill it with blood.
- Remove the band from your arm when enough blood is collected.
- Put a gauze pad or cotton ball over the needle site as the needle is removed.
- Put pressure to the site and then a bandage.
Blood sample from a heel stick
During newborn testing, the blood sample is usually taken from your baby's heel (called a heel stick).
- Your baby's heel is cleaned with alcohol and then the heel is poked with a small needle.
- Several drops of blood are collected inside circles on a special piece of paper.
- When enough blood has been collected, a small bandage is put on the site.
