Adding bacitracin and neomycin to the specimens slightly attenuated the effects of storing lithium heparin-plasma at -21 degrees C, but significant storage effects were still noted by day 14. Processed Volume: 0.2 mL plasma/serum Special Processing: Lab Staff: Centrifuge specimen, remove serum/plasma aliquot into plastic sample cup. Run within 4 hours or store at refrigerated temperatures. Osmolality Serum/Plasma. Order Name OSMO Test Number: 2004300 Revision Date 01/23/2013.

Normal Range =. 285 - 295 mOsm/kg. Serum Osmolality = (2 x (Na + K)) + (BUN / 2.8) + (glucose / 18) DISCLAIMER: All calculations must be confirmed before use. 2016-07-21 The normal range of serum osmolality is 285-295 mOsm/kg. The measured osmolality should not exceed the predicted by more than 10 mOsm/kg. A difference of more than 10 mOsm/kg is considered an osmolal gap.Causes for a serum osmolal gap include mannitol, ethanol, methanol, ethylene glycol and other compounds in very high concentration, usually small molecules and often toxins.

The Serum Osmolality/Osmolarity calculates expected serum osmolarity, for comparison to measured osmolarity to detect unmeasured compounds in the serum.

The test can show whether you have an unhealthy balance of fluids in your body.

Plasma osmolality can be calculated using the formula: In normal people, increased osmolality in the blood will stimulate secretion of antidiuretic hormone (ADH). This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma. A low serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma. Osmolarity is an estimation of the osmolar concentration of plasma and is proportional to the number of particles per litre of solution; it is expressed as mmol/L.
