Haemodialysis-induced changes in red blood cell size-distribution histograms. 
Treatment by haemodialysis may result in changes of the red blood cell size-distribution histograms in most subjects.  After maintenance haemodialysis a statistically significant shift to the left is observed for the mean size distribution histogram in a group consisting of sixteen women.  The shift is in agreement with the finding of significantly higher values for the microcyte fraction, as well as with significantly lower mean cell volume (MCV) values.  No significant changes were observed for the macrocytic fractions of red blood cells.
