Frequently Asked Questions (FAQs):

Q: What is Osmolality?

A:  Osmolality is a measure of the number of dissolved particles in a fluid. A test for osmolality measures the amount of dissolved substances such as sodium, potassium, chloride, glucose and urea in a sample of blood and sometimes in urine.

 

Q: When is it ordered?

A: Testing may be ordered when a person has an unexplained low blood sodium or signs and symptoms that a healthcare practitioner suspects may be due to low blood sodium such as:

  • Excessive thirst
  • Confusion
  • Nausea
  • Headache
  • Lethargy
  • In severe cases, seizures or coma

A urine osmolality test may be ordered along with blood testing when a health practitioner wants to compare urine results with the serum osmolality and/or when the person being tested is producing increased or decreased amounts of urine.
