Fasting plasma glucose levels, serum osmolality and serum concentrations of sodium and potassium were determined in 73 Libyan diabetic patients attending the outpatient clinic of the Diabetes Hospital, Tripoli, Libya. The respective mean values were 234.8 +/- 9.7 mg.dl-1, 288.5 +/- 2 m0sm.L-1, 134.7 +/- 0.8 mEq.L-1 and 4.2 +/- 0.07 mEq.L-1. Statistically significant correlations were present between fasting plasma glucose and serum osmolality as well as the concentrations of serum sodium and potassium. There is is an increase in osmolality and levels of sodium and potassium concentration with an increase in plasma glucose concentration.
