Many modern automated cell counters offer novel parameters. Some of these, such as the CHr, reticulocyte hemoglobin equivalent, or immature platelet fraction, schistocytes have been accepted by many clinicians; the CHr has even become part of clinical practice guidelines for dialysis patients. Other parameters are still research-use only and lack well-defined reference ranges. One important albeit rare clinical problem is to characterize platelet volume in case of inherited thrombocytopenia. Most novel parameters are specific for certain instrument platforms, and results of even similar parameters from different manufacturers are often difficult to compare.
