Sampling blood from the fingertip:
- Choose a different puncture site each time you test. Repeated punctures in the same spot may cause soreness and calluses.
- Before testing, wash your hands and the sample site with warm, soapy water. Rinse and dry completely. Contaminants on the skin may affect results.
1. Puncture your finger
- Hold the lancing device firmly against the side of your finger. Press the release button. Remove the lancing device from your finger.
2. Get a round drop of blood
- Gently squeeze and/or massage your fingertip until a round drop of blood forms.
- NOTE: If the blood smears or runs, Do Not use that sample. Dry the area and gently squeeze another drop of blood or puncture a new site.
