Osmometer

Applications Clinical Applications of Osmometry: • Determine Osmol Gap- actual versus calculated osmolality is a rapid indicator for toxicology and trauma cases. Remember, only freezing point method is sensitive to alcohol and ketones. • Mannitol Treatment- maintain, without exceeding, critical level of therapeutic infusion. • Glycine Ingestion- monitor the absorption of irrigation fluids in surgical procedures. • Differentiate DKA and NKH- only a measured osmolality can make this determination and guide effective therapy. • Renal Function- evaluate concentrating ability and monitor ADH therapy. • Hydration Status for Athletes- weight class and endurance events are conducive to dehydration, with performance and health consequences. • Sample Authentication for Drug Screens- low urine osmolality is indicative of tampering.
