Metabolic / Electrolytes
Also known as: Serum Osmolality, Plasma Osmolality
Seek immediate medical attention if you experience severe confusion, seizures, trouble breathing, or uncontrollable shaking, especially if these symptoms appear suddenly.
This test checks how many tiny bits are floating in the liquid part of your blood. These bits include things like salt, sugar, and a waste product called urea. They all work together to keep your body's fluids in good balance.
Your doctor orders this test to check the water and salt levels in your body. It can help find out why you might be confused or very thirsty. Sometimes, it can also show if you have certain kinds of poisoning.
Reference ranges for serum osmolality can vary by laboratory. Your doctor will interpret your results based on your individual health, age, and other factors.
