Methods of determining concentration of glucose
First Claim
Patent Images
1. A method of determining a concentration of glucose in blood, the method comprising steps of:
- stimulating a region of skin other than the fingertips by manually rubbing the exterior surface of the region for a duration of at least 1 second;
after stimulating the region of skin, creating an opening in the region of skin and furnishing no more than 1 microliter of blood at the opening;
coupling an electrochemical sensor strip to a meter where the sensor strip is adapted to transport and receive a blood sample of no more than 1 microliter from the blood at the opening;
transporting the blood sample of no more than 1 microliter to the sensor strip via an un-pressurized mode of transport; and
determining the concentration of glucose in the blood sample using the electrochemical sensor strip and meter.

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.
