Abstract
A method and apparatus wherein measurement current values output from a first oxygen sensor and a second oxygen sensor are time sequentially measured. Each moving average value is calculated from each sequential measurement current value. Each time differential value is calculated from the pair of each calculated moving average values, by least squares approximation. Then, drug susceptibility is measured based upon each calculated time differential value, so that drug the susceptibility measurement is performed quickly or accurately.
