PARTICIPATION IN RIQAS Participation in RIQAS follows these simple steps: Register the instruments and methods used in your lab by completing the enrolment document. Enrolment documents are available from riqas.com and should be submitted 3 weeks before the cycle starts. Check RIQAS policies in method questionnaire. Analyse the sample on the recommended date, carefully following the instructions for use. Enter your results via RIQAS.Net or on the return sheet and submit electronically, by fax or post before the final deadline. Receive a set of numbered samples along with a username/password to...

STANDARD REPORT Performance data is presented in a one page format with up to seven sub-reports. Text Section: Statistics for all methods, your method and instrument group (programme specific). Method and instrument comparison. Multi-Method Stat Section: Enables assessment of the performance of each method. Levey-Jennings Chart: Details features of your laboratory’s performance. Target Score: This unique chart provides a numerical index of performance, allowing at-a-glance assessment. Helps to identify trends and shifts in performance. Rapid assessment of concentration related biases. 6

TEXT SECTION The text section summarises the statistical information for each parameter. RIQAS performance indicators include SDI, Target Score and %Deviation. Acceptable performance criteria: SDI < 2 Target score 50 %Deviation < defined acceptable limits Performance statement appears here if performance indicators exceed limits Report is presented in your chosen unit. After statistical reduction, some results are excluded. Number of returned results used to generate Mean for Comparison. Average value of all laboratories’ results. Ideally this will be your instrument group mean. If N<5 for instrument...

HISTOGRAM The Bar Graph is intended as a quick visualisation of how your lab’s result compares to the method mean, instrument mean and all method mean. Your instrument group (programme specific) Your method group Total of 673 laboratories reported values between 35.96 and 36.63. RIQAS reports show your unit of measurement. 58 laboratories reported values between 33.29 and 33.96 in your method group. 25 laboratories reported values between 37.96 and 38.62 in your instrument group. Your result is indicated by the black triangle. 8

LEVEY-JENNINGS CHART SDIs reflect laboratory performance in relation to fit-for-purpose SDPAs and are useful to monitor performance over time. Acceptable performance is SDI < 2. Where a result has been returned, the Mean for Comparison for each sample is indicated at the top of the chart. This allows easy assessment of concentration related bias: I: Instrument mean M: Method mean A: All method mean N = No result returned from your laboratory. Sample number. This line indicates a change in registration details for this parameter. Your SDI (Standard Deviation Index). C = Corrected results will be...
