1. An analyte monitoring device operable to draw a fluid sample from a subject, the device comprising:

  • a plurality of microneedles disposed radially outward on a circular carrier, the circular carrier rotatably connected to the device, wherein each of the plurality of microneedles comprises a longitudinal axis and is individually actuatable;

    a plurality of microchannels, wherein each of the plurality of microneedles is at least intermittently in fluid communication with a corresponding microchannel, wherein each of the plurality of microneedles is connected to and moveable with a corresponding fluidic capture site and is configured to collect the fluid sample from the subject, wherein the corresponding fluidic capture site is configured to fluidly couple to and deliver the fluid sample to at least one of the plurality of microchannels, and wherein the plurality of microchannels are on a surface that is transverse to the longitudinal axis of at least one of the plurality of microneedles;

    at least one actuator operable to drive each microneedle and corresponding fluidic capture site in a non-rectilinear path relative to the circular carrier to collect the fluid sample from the subject and to deliver the fluid sample to the at least one of the plurality of microchannels; and

    a controller operable to initiate analyte testing of the fluid sample.
