A method and apparatus for screening or sensing disease states, injury sites or bodily conditions in a human or animal subject by separately detecting the DC biopotential of the electromagnetic field at a plurality of test points in a test area. The DC biopotentials are converted by analog to digital converters connected to DC biopotential test sensors at the test points into digital test signals, and the DC biopotential test sensors and analog to digital converters form a biopotential sensing section which is separate from a processing section that receives and processes the digital test signals. Signals between the processing section and the bopotential sensing section are transmitted by a transmission network which electrically isolates the two sections. The conversions performed by the analog to digital converters are synchronized with the AC line frequency of the apparatus power supply, and the digital test signals are filtered in the processing section by digital filters, each of which is dedicated to an individual DC biopotential test sensor.
