What is the serum osmolality test?
The body will constantly lose water as you breathe, sweat, and urinate. When we don't drink enough water, our blood is enriched with chemicals. That is called . The blood serum in your veins and arteries doesn't contain any blood cells. Serum osmolality tests check for the chemical imbalances in the blood; they measure the level of chemicals in the liquid part of the blood (serum). Various chemicals affect serum osmolality, including sodium, chloride, bicarbonate, proteins, and sugar (glucose).
When is the serum osmolality test recommended?
It is recommended: As a way to check the fluid-to-particle balance in your body. The serum and urine osmolality may be tested in patients with a low sodium concentration in the serum, a high serum sodium concentration, an unusually high urine output, an unusually low urine output, or excessive thirst. It will help to evaluate the body's sodium and water balance and its ability to appropriately produce and concentrate urine.When poisoning is suspected, serum osmolality can help to identify the presence of toxic alcohols.
What does it measure?
The serum osmolality test: Primarily analyses the sodium dissolved in the serum (the liquid portion of blood). Sodium is the major electrolyte in the blood and urine. This works with potassium, chloride, and CO2 (in the form of bicarbonate) to maintain electrical neutrality in the body and acid-base balance. The sodium comes into the body in the diet and is normally conserved or eliminated in the form of urine by the kidneys to maintain its concentration in the blood within a range.The serum osmolality test is often done in cases of suspected poisoning or overdose. Toxins such as methanol, isopropyl alcohol, ethylene glycol, propylene glycol, and acetone, and drugs such as salicylates (aspirin) can also affect osmolality when ingested in sufficiently larger amounts.
How long will the reports take?
You will get the reports within 6 hours after the collection of the blood sample.
