A hand-held test meter for use with an analytical test strip in the determination of an analyte (such as glucose) in a bodily fluid sample (for example, a whole blood sample) includes a housing, a test meter control circuit block, and an electromagnetic interference detection circuit block with an antenna configured to sense electromagnetic fields of a predetermined frequency. The electromagnetic interference detection circuit block is configured to generate a signal representative of an electromagnetic field sensed by the antenna and to provide that signal to the test meter control circuit block. In addition, the test meter control circuit block is configured to interrupt operation of the hand-held test meter when the signal received from the electromagnetic interference detection circuit block is represents an electromagnetic field that interferes with the hand-held test meters operation.
