Abstract
A bodily fluid sampling device is operable to breach the skin surface and allow bodily fluid to emerge from the breach location. The bodily fluid sampling device further evaluates the amount of bodily fluid emerged from breach location and determines whether the amount is sufficient or insufficient for a particular purpose, such as sampling and testing. The determination is accomplished automatically without moving the device. The user may also intervene to perform a variety of tasks following the determination of the amount of bodily fluid.
