- one Multiplate test cell incorporates two independent sensor units.- the increase of impedance due to the attachment of platelets to theelectrodes is detected for each sensor unit separately andtransformed to arbitrary aggregation units (AU) that are plotted againsttime.- the duplicate sensors serve as an internal control- during each measurement Pearson´s correlation coefficient of singlemeasurements of the curves assessed by the two electrode pairs andthe difference of the two AUCs is calculated. The result is flagged ifthe values are outside of the acceptance range (correlation coefficient<0.98, difference to the mean curve >20%)
