Tenderlett® finger incision device contains a surgical stainless steel blade that incises to a controlled, standardized depth. The Tenderlett device creates a small, shallow incision in the finger which cuts more of the capillary bed without cutting too deeply. Blood flows more freely providing a higher quality blood specimen. A permanently retracting blade reduces the risk of an accidental stick. Available in three depths, to allow proper device selection for the appropriate patient.
