- a test strip having one end comprised of an absorbent material and a reagent adapted for detecting blood characteristics indicative of glucose levels, and another end comprised of electrical leads adapted for electronic coupling to the glucometer; and
a test strip adapter configured for coupling the test strip in fluid communication with the sampling port of the intravenous line, the test strip adapter comprising;
a base portion with a platform which has on a top side of the platform an unsealed mounting area, and the bottom side of said platform being joined to a blunt cannula configured for insertion into the sampling port, the blunt cannula providing fluid communication of a blood sample from the sampling port into the mounting area of the platform;
the unsealed mounting area being configured to receive said test strip end comprised of the absorbent material and reagent; and
said unsealed mounting area of the platform terminating at a point that is adapted to permit coupling of the test strip end comprised of electrical leads to the glucometer when the test strip is inserted in said mounting area without having to remove the test strip from the adapter.

Abstract
A fluid sampling system is disclosed comprising a fluid drawing device and a fluid sampling device. In one embodiment, the fluid sampling device has a base portion having a cannula, a handle, and a ridge extending around at least a portion of an outer surface. A top portion has a flange adapted to engage the ridge to couple the top portion to the base portion. In another embodiment, the fluid sampling device has a base portion having a cannula, a handle, a mounting portion, and a test strip coupled to the base portion at least partially within the mounting portion. In yet another embodiment, the fluid sampling device has a test strip housing for receiving an end of a test strip therein. Extending from an end of the test strip housing is a blunt cannula.
