Plasma osmolality vs serum osmolality
WebJun 22, 2024 · The body fluid that we usually use to measure osmolality in humans is serum. Serum is what is left from blood once the cells and proteins have been removed. The particles that make up the osmolality of serum are glucose, sodium and potassium salts (Na + and K +) and urea. The normal serum osmolality is 280-295 mOsm/kg. WebSerum osmolality is a measure of the number of osmotically active solute particles (such as sodium) per kilogram of serum. It can help differentiate between hypertonic …

WebStatistical differences were based on three different international performance criteria. Results: Whole blood stability was higher in the presence of anticoagulant. Serum osmolality was stable for 2days at RT and 8days at 4°C, while plasma was less stable when refrigerated. Urine stability was 5days at RT, 4days at 4°C and >14days when frozen. WebBlood osmolality is primarily a measure of sodium dissolved in the serum. Sodium is the major electrolyte in the blood, urine, and stool. It works with potassium, chloride, and CO2 (in the form of bicarbonate) to maintain electrical neutrality in the body and acid-base balance. Sodium comes into the body in the diet and is normally conserved or ...
