Abstract

An analyte test meter that detects contact between a user and an electrochemical test strip includes a test strip port, a capacitive sensor positioned proximate to the test strip port, and a controller connected to the test strip port and the capacitive sensor. The controller is configured to identify insertion of the electrochemical test strip into the test strip port, apply a drive signal to the capacitive sensor, measure a first response to the drive signal from the capacitive sensor, identify dosing of a fluid sample on the electrochemical test strip, apply the drive signal to the capacitive sensor after the dosing, measure a second response to the drive signal from the capacitive sensor, and detect contact between a body of a user and at least one electrode in the electrochemical test strip in response to a difference between the first and second responses exceeding a predetermined threshold.
