Osmolal gaps in urine.

Osmolal gaps in urine.

Understanding the anion and osmolal gaps laboratory values: what they are and how to use them.

A pseudo course is a course that has a unique name, different from the standard course definition. Courses at The University of Akron are defined numerically, with the dept. number for the first 4 digits, and the actual course number with the last 3 characters. Example: 3300:111------3300 designates the English Dept., and 111 defines the exact course, in this case English Composition I. History...

A retrospective analysis of glycol and toxic alcohol ingestion: utility of anion and osmolal gaps

BACKGROUND Patients ingesting ethylene glycol, isopropanol, methanol, and propylene glycol ('toxic alcohols') often present with non-specific signs and symptoms. Definitive diagnosis of toxic alcohols has traditionally been by gas chromatography (GC), a technique not commonly performed on-site in hospital clinical laboratories. The objectives of this retrospective study were: 1) to assess the d...

Osmolal gap in hemodialyzed uremic patients.

Osmolality is an expression of the number of particles in a given weight of solvent (mOsm). Measured osmolality is determined by the osmometer, and calculated osmolality is estimated by 2xNa + UN/2.8 + glucose/18. The difference between measured and calculated osmolality is the osmolal gap. The purpose of the present study is to determine the measured and the calculated osmolality and the osmol...

Serum sodium and osmolal changes in tuberculous meningitis.

Twenty children from 2 months to 7 years (mean age 2.74 years +/- 1.62) diagnosed to have tuberculous meningitis (TBM) were evaluated for serial serum sodium levels and osmolality of cerebrospinal fluid (CSF), serum and urine on admission and the results compared with 20 age and nutritionally matched controls, and these investigations repeated on day 3 and day 10. Mean serum sodium levels (130....
