Abstract

A disposable lancet combined with a reagent carrying strip which carries a reagent that indicates the concentration of a blood component in a blood sample placed in contact with the strip. The reagent carrying strip is connected to the lancet, e.g. by molding. One end of the lancet is sharpened for piercing the skin. The strip is sheet-like and has a first side and a second side, which sides are both accessible for the user, such that the reagent carrying strip can be inserted into a blood glucose meter. A weakened tear line is provided at a connection between the lancet and an edge of the reagent carrying strip so that the reagent carrying strip may be easily disconnected from the lancet.

Claims

1. A disposable lancet and reagent carrying strip combination comprising:

a lancet; and

a reagent carrying strip comprising;

a sheet having two sides, both of which are accessible to a user and a plurality of edges; and

wherein the lancet is adjacent to one of the edges and is connected to the reagent carrying strip along an edge at a connection having a weakened tear line.

2. A disposable lancet and reagent carrying strip combination as recited in claim 1, wherein the reagent carrying strip is rectangular.
