                            <p>In this paper, pseudocholinesterase, activity which is being determined by various colorimetric methods in our laboratory, is investigated by a manometric method. For this Durvose Warburg Apparatus is used. First, the reaction flask-manometer systems used in the experiments are calibrated with mercury, and the flask constants are calculated. By using reagent blank and acetic acid standard the precision and the accuracy of the method are calculated. Frech sera obtained from 10 healthy persons are tested, and the enzyme activity is found between 51 - 212 p. mole/hour/ml. Precision of the method was 8,7 % (as the coefficient of variation) and accuracy 2,64 (as the mean value of the deviation from real value) .</p></trans-abstract>

Ayıraç körü ve asetik asit standardı ile çalışılarak metodun isabet (precision) ve doğruluk derecesi (accuracy) tayin edildi.
