Let's analyze your Osmolality levels

A few questions help us personalize your report.

About Osmolality

Serum osmolality measures the concentration of dissolved particles in your blood, reflecting your body's fluid balance. It is primarily determined by sodium, glucose, and urea. Abnormal values indicate disrupted fluid homeostasis or the presence of unmeasured osmoles from toxic alcohols.

Also known as: Osm, Osmolality, Plasma Osmolality, Serum Osmolality

What does your Osmolality result mean?

High osmolality indicates dehydration, uncontrolled diabetes, or toxic alcohol ingestion. Low osmolality results from overhydration or SIADH.

Optimal vs. normal range

Standard range is 275-295 mOsm/kg. Functional optimal is 280-290 mOsm/kg.
