WebMay 1, 1998 · Plasma strong-ion difference ( [SID]) was calculated from [Na + ] + [K + ] − [Cl − ] − [La − ]. Total protein concentration was used to derive the total concentration of weak acid ( [A] tot ). [A] tot encompassed a range of 18.7 to 9.0 meq/l, whereas [SID] varied from 48.1 to 26.6 meq/l and was directly correlated with [A] tot.
