Resumo
In this investigation, we intend to determine potassium levels in human blood aiming to study in more details
the common de¯ciencies in Brazilian population helping their diagnostic well as to facilitate the interpretation
of data deriving from clinical practice. The potassium takes part in the human being metabolism and it is
very important for preservation of the osmotic and acid-base equilibria of human °uids, so its variations are
generally associated to pathological processes. The objective of this study is the establishment of reliable
potassium reference value in blood, using EDXRF technique, with emphasis on the statistical treatment. The
samples came from Blood Banks from di®erent parts of Brazil. The biological samples were obtained from
a select healthy group (male and female blood donors), following the procedure conventionally establish for
blood donation. The in°uence of sex and age was evaluated considering several range for age (18-20, 21-30,
31-40, 41-50, 3 51 years). The result is presented following a descriptive statistics procedure, which includes
the evaluation of mean, standard deviation, median and mode. This statistical treatment make possible the
comparison with data derived for di®erent population groups. These results show small di®erences when a
comparison is performed in function of age and sex emphasizing the necessity to adopt ranges.
