`ABSTRACT
`A region of skin, other than the fingertips, is stimulated.
`After stimulation, an opening is created in the skin (e.g., by
`lancing the skin) to cause a flow of body fluid from the
`region. At least a portion of this body fluid is transported to
`a testing device where the concentration of analyte (e.g.,
`glucose) in the body fluid is then determined. It is found that
`the stimulation of the skin provides results that are generally
`closer to the results of measurements from the fingertips, the
`traditional site for obtaining body fluid for analyte testing.
