Since June 1987, a quality control program has been implemented in the hematology and coprology departments of the clinical laboratory of the Juan José Arévalo Bermejo General Hospital of the Social Security Institute. During this program, the technical staff who rotated through these areas after six months were evaluated. All laboratory technicians had been in these areas at least once, which allows for calculating their own variability. A graph is created for each technician, for each area (hematology or coprology). The concept used, variability, translates to the standard deviation of the results for each technician, understood as the difference between the results obtained in a patient sample and its duplicate, using the latter as a control sample, with a different name or code not recognized by the processing technician. The graphs in the hematology area are called vertical linearity graphs (quantitative) and the graphs in the coprology area are called horizontal linearity graphs (qualitative). These two variations, mainly the latter, can be implemented in the areas of urology and serology.
