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 and is method specific. Although good precision suggests good accuracy, precise results can be inaccurate. -

7.3. CUVETTE PREPARATION Proper mixing is very important for reproducibility of the measurements. The proper mixing technique for each method is listed in the method procedure. Invert the cuvette a couple of times or for a specified time: hold the cuvette in the vertical position. - Page 20 Do not let the reacted sample stand too long after reagent has been added. For best accuracy, respect the timings described in each specific 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.
