Patent ID: 8409113

Claim:
A method of obtaining a body fluid sample from a living body and using the body fluid sample comprising: removing a body fluid sampling implement from an interior of a container, the body fluid sampling implement comprising a reagent containing part comprising a reagent adapted to interact with a predetermined component in the body fluid, the interior of the container also containing a needle possessing a sharp needle point at a distal end of the needle; mounting the body fluid sampling implement on a component measuring device, the component measuring device being adapted to measure at least one of a quantity and a property of the predetermined component of the body fluid obtained by the body fluid sampling implement; the body fluid sampling implement being removed from the interior of the container either before mounting the body fluid sampling implement on the component measuring device or after mounting the body fluid sampling implement on the component measuring device; puncturing a surface of the living body with the needle by moving the needle relative to the container to produce a body fluid sample; and introducing to the reagent containing part of the body fluid sampling implement the body fluid sample obtained by puncturing the surface of the living body with the needle so that the reagent interacts with the predetermined component in the body fluid sample.
