[Ion chromatographic determination of inorganic anions in human serum].
The ion chromatographic method is a rapid and reliable technique for the simultaneous determination of inorganic anion concentrations in serum. We are investigating the effects of various diseases on the serum levels of the following inorganic anions: phosphate, bromide, nitrate, and sulphate. In this paper, we tested the intra- and intermeasurement reproducibility of the ion chromatographic method using pooled normal human serum. We found a good intrameasurement reproducibility for all of the above inorganic anions. The intermeasurement reproducibility was good for three of the inorganic anions but not for nitrate. We measured the serum levels of these inorganic anions in 241 inhabitants in one rural area. Using sera of normal inhabitants chosen from the above group, we used the mean value plus or minus two standard deviations as the normal range of each inorganic anion. Our values are in agreement with previously published reports. We found that the serum levels of nitrate and sulphate tended to be increased in inhabitants with liver or kidney disfunction respectively.
