Incision vs. Lancet

Our patented devices perform a gentle, sweeping arc incision (left image) above the level of sensitive nerve fibers. The blade permanently retracts back into the device, eliminating any chance of an accidental stick and creates a high quality incision resulting in a sample free of tissue contamination. Our devices are safe, easy to use, and virtually pain free with less bruising as compared with traditional lancet devices (right image).
