Abstract
This disclosure concerns a sampling device and a system for collecting body fluid, comprising a metal lancing unit having a distal tip suitable for piercing skin and a capillary channel extending between the tip and a proximal section of the lancing unit for collecting body fluid; and further comprising a plastic holding unit affixed to the lancing unit for manipulating the lancing unit in order to form an incision in the skin, wherein the holding unit contains a sorbent adapted for sorption of moisture and/or volatile substances to protect the sampling device from degradation prior to use.
