For both finger and heel sticks, the first drop of blood produced should not be used and should be wiped away since it contains interstitial fluid which aids in the clotting process.
The first drop of blood contains tissue fluid that may contaminate or dilute the blood specimen and affect test results. The recommended depth of incision is about 2 mm, anything deeper will present the risk of nerve or bone damage and should be avoided. Tightly squeezing the area will cut the blood flow and should be avoided.
Avoid extreme side and tip of finger.
After the site is properly cleansed, a spring loaded safety lancet is recommended for use. Applying gentle pressure to the area and releasing will produce a better blood flow.

Label specimen Specimen must be labeled in the presence of the patient. Never use a moist cloth that has been heated in a microwave as this may cause injury to the patient. Finger stick For a finger stick, the cut should be made perpendicular to the fingerprint line. Tap the container gently on a hard surface to move blood further down into the tube if necessary. Heat should be applied for minutes. If necessary, seek assistance for finger puncture if the patient is a small child. Cleanse hands and put on gloves Use soap and water or alcohol-based gel to cleanse hands. A previous puncture site should be avoided because of increased possibility of infection.
