A system and method for detecting a measuring an analyte in a biological fluid
of an animal. A harvesting device (10) is provided suitable for positioning
on the surface of tissue of an animal to harvest biological fluid therefrom. The
harvesting device (10) comprises an analyte sensor (50) positioned
to be contacted by the harvested biological fluid and which generates a measurement
signal representative of the analyte. At least one attribute sensor (40)
is provided to measure an attribute associated with the biological fluid harvesting
operation of the harvesting device (10) or the assay of the biological fluid,
and which generates an attribute signal representative of the attribute. Adjustments
are made to operational parameters of the harvesting device (10) based on
the one or more attributes.
