Laboratory analyst/manager Clause Samples

Laboratory analyst/manager. For the majority of Proficiency Testing schemes, reports are usually sent, in the first instance, to the laboratory manager or analyst responsible for the work, since they are familiar with the operation of the PT scheme. It is recommended, by most schemes, that the results from any distribution are studied in conjunction with the scheme protocol or participants’ instructions. In particular, the performance scoring system used in the scheme needs to be clearly understood. If this is unclear from any documentation provided by the co-ordinator, the co-ordinator should be contacted to clarify matters. Laboratory staff should always check that the results in the report are those submitted by the laboratory, and whether the results in the report indicate satisfactory, unsatisfactory or questionable performance. If there is any doubt regarding the validity of the results in the report the co-ordinator should be contacted to resolve the situation. Where an unsatisfactory performance score has been obtained for any analyte(s), it is recommended that the laboratory ascertain possible causes (see par. 5.2 for factors that might be of interest). Furthermore, the range, specificity and sensitivity of the method should be considered when interpreting a given z score. Data in the mid-range of the method, producing a questionable z score is of more concern than when the data are at or near the limit of detection, or at the top end of the range of the method. The precision of the method is usually less well-defined at the extremes of its range. The laboratory may be able to use results obtained in this situation to assess the validity of its current method. Poor performance could lead to the rejection of the method for a particular analysis.
