1. A method of assessing a bodily fluid sample on a test strip, the method comprising:
applying a periodic signal with a first electrode located at a first location in a microfluidic channel of the test strip;
monitoring the applied periodic signal with a second electrode located at a second location in the microfluidic channel;
using a third electrode located at a third location in the microfluidic channel as a reference electrode, wherein each of the first electrode, the second electrode and the third electrode has a fixed function;
collecting the bodily fluid sample in the microfluidic channel while continuing to apply the periodic signal, monitor the periodic signal and use the third electrode as a reference electrode; and
determining that the bodily fluid sample is a sufficient volume for analyzing by identifying a period of stability in the monitored periodic signal, based at least in part on the applying and monitoring of the periodic signal.
