Page 9: Precision & Accuracy
5.3. PRECISION & ACCURACY Precision is how closely repeated measurements are to one another. Precision is usually expressed as standard deviation (SD). Accuracy is defined as the closeness of a test result to the true value. Although good precision suggests good accuracy, precise results can be inaccurate. The figure explains these definitions. -

7.2. CUVETTE PREPARATION Proper mixing is very important for reproducibility of the measurements. The proper mixing technique is listed in the method procedure. The mixing method is indicated with “swirl“ using one of the following icons: In order to avoid reagent leaking and to obtain more accurate measurements, close the cuvette first with the supplied HDPE plastic stopper and then the black cap. - Page 20 Do not let the reacted sample stand too long after reagent has been added. For best accuracy, respect the timings described in the method. It is possible to take multiple readings in a row, but it is recommended to take a new zero reading for each sample and to use the same cuvette for zeroing and measurement when possible.
