“…Specifically, methods of ionized magnesium measurement were atomic absorption by Perkin‐Elmer instrument in United States study, 41 automated potentiometric analyzer (the NOVA 8 electrolyte analyzer [NOVA Biomedical, Mississauga, ON, Canada]) in the Canadian study in whole blood, 42 and Olympus AU 400 Chemistry auto analyzer in India (CLSI C28‐A2) 31 . Pruden et al 46 demonstrated that RIs observed by photometric method were higher than those observed by flame/atomic absorption methods, though our RI which was obtained by photometric method was lower than other countries. In addition to analytical considerations, gastrointestinal absorption and urinary excretion are known to influence serum magnesium levels 47 .…”

Introduction The aim of this study was to establish RIs for clinically important markers including superoxide dismutase (SOD), serum copper, zinc, calcium, magnesium, and phosphate in a cohort of healthy Iranian adults. Materials A subsample from MASHAD cohort study was used to assess serum SOD, copper, zinc, calcium, magnesium and phosphate. Serum SOD was measured according to its inhibitory potential of pyrogallol oxidation. Micro‐ and macro‐minerals were measured using flame atomic absorption spectrometry and a BT3000 autoanalyzer, respectively. Sex‐ and age‐specific RIs were then calculated based on CLSI Ep28‐A3 guidelines. Results Reference value distributions for studied parameters did not demonstrate any age‐specific differences that were statistically significant. In addition, sex partitioning was not required for all parameters, apart from serum magnesium, which showed a wider range in females (0.81–1.26 mg/dl) compared with males (0.82–1.23 mg/dl). Conclusion The RIs established in this study can be expected to improve mineral assessment and clinical decision‐making in the Iranian adult population.

Serial magnesium determinations by atomic absorption spectrophotometry were performed in the first five days of age on the serum of 91 infants with birth weights less than 2.0 kg (4.4 lb). There was a gradual rise in Mg levels with postnatal age, in both preterm infants with birth weights appropriate for gestational age and infants who were small for gestational age. Decreased Mg levels were observed in infants who were small for gestational age, and in infants born of toxemic mothers and primiparous mothers. There was an inverse relation between Mg levels and gestational age. There was no significant correlation between Mg levels and serum calcium, phosphorus, or protein levels. The mean of all determinations was 2.26 mg/100 ml \m=+-\SD 0.34. These figures are similar to adult values. Three infants with serum Mg values below 2 SD from the mean exhibited signs of increased neuromuscular irritability. The low Mg levels reverted to normal without treatment.
