Claim:
1. A method of electrochemically determining a concentration of an analyte in a blood sample, comprising: manually rubbing a region of skin other than a fingertip for at least 1 second, after manually rubbing, lancing the region of skin to provide no more than 1 microliter of a blood sample on the surface of the region of skin; contacting a sensor coupled to a meter to the blood sample to transport the blood sample to a sample chamber of the sensor, the sample chamber for holding the blood sample and comprising: determining when the sample chamber is beginning to fill with the blood sample by detecting a signal between the first electrode and the second electrode; determining when the sample chamber is substantially filled with the blood sample by detecting a signal between the first electrode and the third electrode; and electrochemically determining the concentration of the analyte in the blood sample using the sensor and meter.
