Biological fluid sample assessment

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 reconfigurable 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;
• switching configurations of the first electrode, the second electrode and the third electrode, while collecting the bodily fluid sample;
• and
• determining that the bodily fluid sample is sufficient for analyzing, based at least in part on the applied and monitored periodic signal.

A method of assessing consistency and reducing the sensitivity of a measurement of a bodily fluid sample on a test strip with at least four electrodes, the method comprising:

• applying a periodic signal with at least some of the at least four electrodes, wherein the at least four electrodes are located at different locations in a microfluidic sample chamber of the test strip;
• monitoring the periodic signal with at least some of the at least four electrodes;
• collecting the bodily fluid sample on the test strip;
• identifying a period of stability in the monitored signals;
• and
• initiating measurement of the bodily fluid sample, based on the identified period of stability.
