Abstract

Cartridge for a testing device and method of testing using the testing device with the cartridge. The cartridge includes a plurality of lancet needles and a mechanism allowing the cartridge to be mounted to the testing device. The method provides for puncturing a surface of skin using the testing device by arranging the testing device adjacent against a user'"'"'s skin, triggering the testing device so that one of the plurality of lancet needles is caused to penetrate the user'"'"'s skin, and rotating the cartridge to another position. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
