1. A sampling module, comprising:
- a module body portion that includes a lancet channel;
a lancet with a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel to provide for a lancet to travel in a linear axial movement;
a sterility barrier that is pierceable by the lancet; and
a sample chamber in fluid communication with a sample input port of the module body portion wherein the sample chamber has a volume no greater than 1 microliter.
