Abstract

A control solution packet for calibrating a bodily fluid sampling device includes a container, a control solution pressurized within the container, and a membrane for covering and sealing the container. The control solution can be pressurized before or during calibration so as to ensure the appropriate amount of control solution is delivered to the bodily fluid sampling device. The control solution is manufactured to have a viscosity that controls delivery of the control solution to the device. The membrane is permeable by a piercing device of the bodily fluid sampling device and seals around the piercing device during calibration. In another aspect, the container is in the form of a capsule or dosing attachment that contains the control solution along with a sponge-like material.
