1. A body fluid sampling device comprising:
- a cartridge containing a plurality of penetrating members;
a drive force generator coupled to a processor and configured to be coupled to an active one of said penetrating members and to move said active one of said penetrating members;
the processor configured to provide information relative to a depth of penetration of said active one of said penetrating members through a skin surface when said active one of said penetrating members is moved; and
a plurality of analyte detecting members each associated with one of said penetrating members, the plurality of analyte detecting members being attached to a bottom surface of said cartridge, wherein a first portion of the analyte detecting members measure a first analyte and a second portion of the analyte detecting members measure a second analyte.

Abstract
A plurality of Point-of-Care (POC) tests on a single cartridge (300) is provided such that sequential or nonsequential tests may be performed in an integrated fashion without changing the test cartridge. Each cartridge can contain a penetrating member sensor (302) combination in a radial disk format, interrogated and read by a single illumination/detection device. Alternatively a series of tests can be measured electrochemically and reported. Only those tests, which are required at the time, the sample is taken need to be reported, though all tests are carried out.

20. A device for body fluid sampling usable with a cartridge housing a plurality of penetrating members, the device comprising:
-
a housing; a penetrating member driver coupled to said housing and for use with said cartridge; a processor for controlling said penetrating member driver to move at least one of said penetrating members at velocities which conform with a selectable velocity profile; a storage area having a sensing area; another storage area having an enzyme area separate from the sensing area prior to piercing; wherein said penetrating member pierces opens both storage areas upon member actuation and causes body fluid to first flow to the enzyme area and then to the sensing area.
