Abstract
An method for determining sample volume sufficiency of an electrochemical test strip having a reaction portion and two electrodes, wherein parts of the two electrodes are respectively disposed on the reaction portion, includes: placing a sample on the reaction portion; applying a first voltage to the sample for a first time period to drive a first current between two electrodes; applying a second voltage to the sample for a second time period to drive a second current between the two electrodes; calculating an absolute value of the ratio of a value of the first current to a value of the second current as a sample volume index; and comparing the sample volume index with a predetermined index range to determine if a volume of the sample is insufficient to measure accurately at least one characteristic of the sample.
