Background Many studies have assessed the predictive accuracy of serum osmolality
equations. Different approaches for selecting a usable equation were compared using thirty …

Background Plasma osmolality is a physic and chemical property of interest in emergency
medicine. This magnitude can be measured at the laboratory, but it is usually estimated with …

Background Many different equations have been previously described to estimate plasma
osmolality. The aim of this study is to compare 14 of these equations, in order to determine …

The osmolal gap (OG) 1 is calculated in the emergency department (ED) when ingestion of
ethylene glycol, methanol, isopropyl alcohol, acetone, or other osmotically active substances …

Background: There are several methods for calculating serum osmolality, and their
accordance with measured osmolality is the subject of controversy. Methods: The …

Background: Plasma osmometry and the osmol gap have long been used to provide
clinicians with important diagnostic and prognostic patient information. Objective: We …

Osmolal gap is the difference between the measured osmolality and a calculated osmolality
based on the major commonly measured osmotically active particles. The perceived gap …

We wish to comment on reference intervals for the serum anion gap and osmolality. The
serum anion gap, which is most commonly defined as AG Na-Cl-TCO2, traditionally has had …

Background Serum osmolality levels are measured to determine acid–base and electrolyte
imbalance in serum. In cases where measurement is not possible, the serum osmolality …

Introduction: Serum osmolality is an essential laboratory parameter to understand several
clinical disorders such as electrolyte disturbances, exogenous intoxication and hydration …
