Avoid placing your thumb or fingers over the uncapped end of the safety lancet. 2. Hold the safety lancet against the puncture site. Note: Before using a single-use auto-disabling safety lancet for blood sampling, wash both hands with soap and warm water and disinfect the puncture site with a topical skin antiseptic such as an alcohol swab. 3. Gently press the safety lancet against the puncture site to lance the skin. Listen for an audible click. This indicates that the safety feature of the device has been activated. Dispose of the lancet in an appropriate biohazard sharps container. Please see the Caution Statement. 4. Gently massage from the surrounding area toward the puncture site to collect the required blood volume. For the greatest reduction in pain, lance on the sides of the fingertips. Rotation of sites is recommended. Repeated punctures in the same spot can make fingers sore and callused. Caution Statement • Do not use the single-use auto-disabling safety lancet if the cap is missing or loose. • Always use a new, sterile single-use auto-disabling safety lancet. Do not reuse the single-use auto-disabling safety lancet. • Avoid getting the single-use auto-disabling safety lancet dirty with hand lotion, oil, dirt or debris. • Single-use auto-disabling safety lancets appropriate biohazard sharps container. If a biohazard sharps container is not available use a heavy duty plastic container such as a laundry detergent bottle. Ensure the container is leak-resistant and has a hard puncture proof lid. Do not place loose sharps into the trash and do not flush down the toilet. Do not place sharps into the recycle bin as they are not recyclable.
