What does the Serum Osmolality (Osmolality) - Osmolality blood test mean? Get a free analysis of your blood test now. Here's what you get with our free analysis:
Serum osmolality measures the concentration of dissolved particles in blood serum. It's crucial for assessing hydration status, electrolyte balance, and kidney function. This test helps diagnose conditions like dehydration, overhydration, diabetes insipidus, and certain poisonings. It's also useful in monitoring treatment effectiveness for these conditions. Osmolality is influenced by sodium, glucose, and urea levels in the blood. Changes in osmolality can affect cellular function and fluid distribution throughout the body, making it an important indicator of overall health and metabolic balance.
A low serum osmolality reading (below 275 mOsm/kg) may indicate:
Low osmolality can lead to cellular swelling and potentially serious complications, especially in the brain. It requires prompt medical attention to identify and treat the underlying cause.
A high serum osmolality reading (above 295 mOsm/kg) may indicate:
High osmolality can lead to cellular dehydration and potentially serious complications. It requires prompt medical attention to identify and treat the underlying cause, often involving fluid and electrolyte management.
