摘要
background: considering the significant frequency of hemoglobinopathies in the brazilian population and the necessity of establishing a reliable methodology, quick, reproductive and possible to be applied in a large number of samples, it was the objective of this work to analyze the differences on electrophoretic procedures with cellulose acetate and acid agar compared with isoelectric focusing (ief), and to establish a standard of migration, presenting main positions of abnormal hemoglobin, based on brazilian population hemoglobin. material and method: the studied material was formed by blood samples from laboratory patients and blood donors of sˋo paulo state central area, brazil, and applied laboratory routines tests. for a reasonable comparison and validation of laboratory tests, we related the results with isoelectric focusing. results and discussion: these observations added to literature accounts allowed the establishment of standards of migration all over hemoglobinopathies observed in the brazilian population. in this way, charts were developed to demonstrate the simplicity and viability of this techinique by different laboratories.
