The indirect approach to determine reference intervals refers to a statistical analysis of already existing results from specimens which were collected for routine purposes (for example, samples collected for screening, diagnostic or monitoring purposes). If three to four samples are outside the reference range, a further 20 new samples must be taken and measured. These studies were performed on a variety of Sysmex haematology analyser models and the reference ranges evidently differ according to the populations involved.
