Blood test

The health professional taking a sample of your 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.
• Apply a gauze pad or cotton ball over the needle site as the needle is removed.
• Apply pressure to the site and then a bandage.

Urine test

• Collect a urine sample in a clean container.
• Follow the manufacturer's directions on the bottle of test strips or tablets.
• Avoid getting toilet paper, pubic hair, stool, menstrual blood, or other foreign matter in the urine sample.
