The osmolal gap: what has changed?

Serum osmolality was calculated by use of several equations (2-5 ), and a general correction for ethanol was included. Because large OGs have been observed in renal failure (2 ), we assessed the renal function of each subject by use of the Modification of Diet in Renal Disease equation to estimate t...

Zusammenfassung:	Serum osmolality was calculated by use of several equations (2-5 ), and a general correction for ethanol was included. Because large OGs have been observed in renal failure (2 ), we assessed the renal function of each subject by use of the Modification of Diet in Renal Disease equation to estimate the glomerular filtration rate (eGFR). [...] the equation used to calculate serum osmolality must be considered when evaluating the OG.
