Normal blood magnesium levels in volunteers of Rawalpindi by atomic absorption absorption technique

Magnesium levels in whole blood samples of 67 healthy volunteers (mean 6.46 -+ 0.221; range 1.345 - 13.163 mg/dL) of Rawalpindi district have been determined by flame atomic absorption spectrophotometric method. Magnesium levels of 41 male and 26 female subjects including doctors, nurses, patients attendees, medical students, sweepers and peons of Rawalpindi Medical College and Rawalpindi General Hospital revealed the normal mean blood levels of 6.088 - + 0.258 mg/dL (range 1.345 - 10.679 mg/dL)and 7.060 -+ 0.375 mg/dL (range 4.495 - 13.163 mg/dL),P<0.05 respectively. Only 10 male volunteers were smokers exhibiting 6.768 -+ 0.558 mg/dL (range 4.466 -10.679 mg/dL). Significant relationship was found in magnesium levels between males and females of poor socio-economic group (P<0.05). No relationship occurred between male smokers and non-smokers and magnesium levels in the age groups of males or females or both, when data was compared by 't' test. (author)
