Osmolality
Calculated Serum Osm
For education. Check every result.
Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.
How it is calculated
Calculated Osm = 2×Na + Glucose/18 + BUN/2.8. Normal: 280-295.
About
Serum osmolality calculated from sodium, glucose and urea, for comparison with a measured value.
