ANNEX CHAPTER I: GENERAL CRITERIA Introduction For the objective evaluation of residue-detection procedures, quantitative data on some standard characteristics of the procedures must be available. In addition, quantitative requirements must be laid down for certain of these characteristics which take into account, inter-alia, the purpose of the method (e.g. screening, quantitative determination, confirmation). In this chapter the criteria laid down in the Annex to Directive 85/591/EEC are defined as they shall be applied to the examination of routine methods for the analysis of residues of substances having a hormonal action and of substances having a thyrostatic action. Definitions (i) Specificity Specificity is the ability of a method to distinguish between the analyte being measured and other substances. This characteristic is predominantly a function of the measuring principle used. Details concerning specificity must relate at least to any substances which might be expected to give rise to a signal when the measuring principle described is used, e.g. homologues, analogues, metabolic products of the residue of interest. From the details concerning specificity, it must be possible to derive quantitatively the extent to which the method can distinguish between the analyte and the other substances under the experimental conditions. (ii) Accuracy Accuracy in this document refers to accuracy of the mean. The definition which shall be used here is laid down in ISO 3534-1977 under 2.83 (Accuracy of the mean: the closeness of agreement between the true value and the mean result which would be obtained by applying the experimental procedure a very large number of times). Note: The principal limitations on accuracy are: (a) random errors; (b) systematic errors, e.g. low recovery. For a very large number of experiments, the accuracy of the mean approaches the systematic error. For desk review of a method, the number of experiments must be specified. The measure of accuracy to be used is the difference between the mean measured value for reference material and the true value, expressed as a percentage of the true value. (iii) Precision; repeatability intra-laboratory (within laboratory) and reproducibility inter-laboratory (within and between laboratories) variabilities. The general statistical term 'precision' shall be used as defined in ISO 3534-1977, 2.84 (Precision: the closeness of agreement between the results obtained by applying the experimental procedure several times under prescribed conditions). According to the Annex to Directive 85/591/EEC, the precision values for methods of analysis which are to be considered for adoption under the provisions of that Directive shall be obtained from a collaborative trial which has preferably been conducted in accordance with ISO 5725-1986. For this purpose, the terms repeatability and reproducibility are defined in ISO 5725-1986. For the purpose of preselection of candidate methods by desk review, it is sufficient that data on repeatability are available. For this purpose, the term repeatability is used here as defined in ISO 3534-1977 under 2.85 (a) (Repeatability: the closeness of agreement between successive results obtained with the same method on identical test material, under the same conditions (same operator, same apparatus, same laboratory and short intervals of time)). The measure of repeatability to be used is the coefficient of variation as defined in ISO 3534-1977, 2.35 (Coefficient of variation: the ratio of the standard deviation to the absolute value of the arithmetic mean). (iv) Limit of detection The limit of detection is the smallest measured content from which it is possible to deduce the presence of the analyte with reasonable statistical certainty. It is equal to the mean of the measured content of representative blank samples (n20) plus three times the standard deviation of the mean. Note: If it is to be expected that factors such as species, sex, age, etc. may influence the characteristics of the method, then a set of blank samples is required for each individual homogeneous population to which the method is to be applied. (v) Sensitivity Sensitivity is a measure of the ability of a method to discriminate between small differences in analyte content. In this document, sensitivity is defined as the slope of the calibration curve at the level of interest. (vi) Practicability and applicability Practicability is a non-standard characteristic of an analytical procedure. It is dependent on the scope of the method and is determined by requirements such as sample throughput and costs. Applicability is a list of the commodities to which the candidate method can be applied as presented or with minor modifications. (vii) Other criteria which may be selected as required Limit of decision The limit of decision is the lowest analyte content which, if actually present, will be detected with reasonable statistical certainty and can be identified according to the identification criteria of the method. If both accuracy and precision are constant over a concentration range around the limit of detection, then the limit of decision is equal to the mean of the measured content of the representative blank samples plus six times the standard deviation of the mean. Limit of quantification The limit of quantification is the smallest measured content above which a determination of the analyte is possible with a specified degree of accuracy and repeatability (within laboratory). Requirements as regards accuracy and repeatability Accuracy: In the case of repeated analysis of the reference sample, the deviation of the mean from the true value, expressed as a percentage of the true value, shall not lie outside the following limits: 1.2 // // limits // - true value up to 1 mg/kg: // -50 % to +20 % // - true value over 1 mg/kg and up to 10 mg/kg: // -30 % to +10 % // - true value over 10 mg/kg: // -20 % to +10 % Repeatability: In the case of repeated analysis of the reference sample, the coefficient of variation (C.V.) of the mean shall not exceed the following values: 1.2 // // C.V. // - mean up to 1 mg/kg: // 0,30 // - mean over 1 mg/kg and up to 10 mg/kg: // 0,20 // - mean over 10 mg/kg: // 0,15 Calibration curves If the method depends on calibration curves, then the following information must be given: - the mathematical formula which describes the calibration curve, - numerical values of the parameters of the calibration curves with 95 % confidence intervals (under optimal conditions), - acceptable ranges within which the parameters of the calibration curve may vary from day to day, - the working range of the calibration curve, - details of the variance of the variables which is valid at least for the working range of the calibration curve. Susceptibility to interference For all experimental conditions which could in practice be subject to fluctuation (e.g. stability of reagents, composition of the sample, pH, temperature) any variations which could affect the analytical results shall be indicated. If it is known that certain substances can interfere with the determination of the analyte, this shall also be indicated, together with any suggested means of overcoming the problem. It is of prime importance that any interference which might arise from matrix components should be investigated. Therefore, at least the largest sample equivalent which has no interfering effect on the determination of the analyte (after any specified sample 'clean-up') shall be indicated. Relationship between tolerance values and analytical limits For substances with a zero tolerance, the limit of decision of the analytical method must be sufficiently low that residue levels which would generally be expected after illegal use will be detected with at least 95 % probability. For substances with a tolerance level, established at the maximum natural physiological level, the limit of quantification shall not exceed that tolerance minus three times the standard deviation which the method produces for a sample at the tolerance level. Reference material A reference material is a sample of substance or a single manufactured object of which one, or several, properties are determined with sufficient accuracy, so that it can be used to calibrate an apparatus or to verify a method of measurement. The certification must be based on a technically valid procedure. If no reference material is available, relevant parameters may be evaluated by analysing fortified sample material.

The quality criteria are designed for qualitative analysis and aim to prevent false positive results. For a positive conclusion, the analytical results have to fulfil the quality criteria laid down for the detection method applied. // 3. // Definitions regarding the presence of an analyte // 3.1. // Analyte: a component of a test sample the presence of which has to be demonstrated. The term 'analyte' includes derivatives formed from the analyte during the analysis wherever this is applicable. // 3.2. // Standard material: a well-defined substance in its highest attainable purity to be used as a reference in the analysis. // 3.3. // Positive: the presence of the analyte in the sample is proved, according to the method, when the general criteria, and the criteria specified for the relevant detection method, are fulfilled. The result of the analysis is 'positive'. // 3.4. // Negative: the result of the analysis is regarded as 'negative' if the criteria specified for the relevant method are not fulfilled or the analysis does not indicate the presence of the analyte in the sample above the limit of decision. // 3.5. // Co-chromatography: the following procedure is applied. The purified test solution prior to the chromatographic step is divided into two parts: // // (a) one part is chromatographed as such; // // (b) the standard material that is to be identified is added to the other part, and this mixed solution of analyte and standard material is chormatographed. // // The amount of added standard material has to be about equal to the estimated amount of the analyte. // 4. // General considerations for the whole analytical procedure // 4.1. // General criteria for the whole procedure // // The method must have been proved to be able to distinguish between the analyte and all known interfering materials in the appropriate matrix. // // The physical and chemikl behaviour during the analysis of the analyte should be indistinguishable from that of the corresponding standard material in the appropriate matrix. // 4.2. // General criteria for separation techniques // // Reference samples containing known amounts of analytes must be carried through the entire procedure simultaneously with each batch of test samples analysed. Alternatively, an internal standard may be added to test samples. // 4.3. // Criterion for off-line physical and/or chemical preconcentration, purification and separation, if applied // // The analyte should be in the fraction which is characteristic for the corresponding standard material in the appropriate matrix material. // 4.4. // Criterion for on-line separation, if applied (e.g. GC) // // The analyte should elute at the retention time which is characteristic for the corresponding standard material in the appropriate matrix material. // 4.5. // Preparation of the test sample // // The test sample should be prepared from the laboratory sample in such a way that there is a maximum chance of detecting the analyte, if present. // 4.6. // Preparation of the test portion // // The test portion would be prepared from the test sample in such a way that there is a maximum chance of detecting the analyte, if present. // 5. // Quality requirements for determination of an analyte by RIA // // For screening purposes: // 5.1. // The working range of the calibration curve has to be specified and has in general to cover a concentration range of at least one decade. // 5.2. // Control samples have to be included in each assay.

Notes 1. Relative intensities of some of the above ions are too low (around 10 %) to be used reliably for confirmation. 2. Relative intensities of the ions may vary with amount of analyte injected onto the column. In the case of diethylstilboestrol at low concentrations under methane CI, the 661 ion becomes the base peak (i.e. there is less fragmentation to the mono-HFB form). It is therefore important to compare the relative ion intensities for the analyte with those for a reference standard at about the same concentration. 3. Ionization with methane results in cleavage of the hexoestrol molecule. The fragment ions of lower mass are not well separated from co-extractives.
