Precisely guided lancet

A lancet having one or more portions of the shank of the lancet blade exposed for direct engagement with cooperating portion(s) of the lancet carrier of a lancing device. This direct engagement of the lancet blade with the lancet carrier provides more precise positional control of the location of the lancing site by eliminating the effect that any variation in the position of the lancet blade within the lancet body would otherwise have on the positioning of the lancet tip. Tolerance stack-up is thereby reduced and accuracy is improved, reducing the necessary sample size and minimizing pain resulting from the lancing operation.
