badania odzysku
Odzysk metody badawczej
Odzysk jest określany jako część analitu dodanego przed analizą do badanej próbki (próbki wzbogaconej lub domieszkowanej), określona na podstawie pomiaru analitu w próbce wzbogaconej i niewzbogaconej. Badanie odzysku wykonuje się przez analizę 6 powtórzeń próbek kontrolnych i takich samych próbek wzbogaconych dodatkiem danego analitu w określonym zakresie stężeń lub materiału odniesienia (przynajmniej analiza próbek o 3 różnych poziomach stężeń substancji dodanej w 6 powtórzeniach). Wymagania dotyczące akceptowalnego odzysku są określone we właściwych metodach badawczych lub w piśmiennictwie fachowym.

recovery experiment
Recovery Experiment
Recovery studies are a classical technique for validating the performance of an analytical method. However, their use in clinical laboratories has been fraught with problems due to improper performance of the experiment, improper calculation of the data, and improper interpretation of the results. Recovery studies, therefore, are used rather selectively and do not have a high priority when another analytical method is available for comparison purposes. However, they may still be useful to help understand the nature of any bias revealed in the comparison of methods experiment. In the absence of a reliable comparison method, recovery studies should take on more importance.
Purpose
The recovery experiment is performed to estimate proportional systematic error. This is the type of error whose magnitude increases as the concentration of analyte increases. The error is often caused by a substance in the sample matrix that reacts with the sought for analyte and therefore competes with the analytical reagent. The experiment may also be helpful for investigating calibration solutions whose assigned values are used to establish instrument set points.
Factors to consider
The experimental procedure is outlined in the accompanying figure. Note that pairs of test samples are prepared in a manner similar to the interference experiment. The important difference is that the solution added contains the sought for analyte (shown as A) rather than an interfering material (shown as I in earlier figure). The solution added is often a standard or calibration solution of the sought for analyte. Both test samples are then analyzed by the method of interest.
