1. A test system comprises:
a test container array including a plurality of test containers;
a plurality of electrodes integrated into the test container array, wherein a set of electrodes of the plurality of electrodes is integrated into a test container of the test container array;
a plurality of drive-sense circuits coupled to the plurality of electrodes, wherein a set of drive-sense circuits of the plurality of drive-sense circuits is coupled to the set of electrodes, wherein an electrode of the set of electrodes is coupled to a drive-sense circuit of the set of the drive-sense circuits via a single line and wherein the drive-sense circuit is operable to simultaneously both drive and detect a change in electrical characteristics of the electrode via the single line;
a processing module operably coupled to:
receive, from the set of drive-sense circuits, a set of changes in electrical characteristics of the set of electrodes; and
interpret the set of changes in electrical characteristics of the set of electrodes as a set of impedance values representative of electrical characteristics of biological material present in the test container; and
a communication module operably coupled to communicate the electrical characteristics of the biological material.
