A patient in the Intensive Care Unit (ICU) has a computed serum osmolality of 320mOsmol/kg H20. The attending physician requested for a confirmatory testing on an Osmometer which gives a 386mOsmol/kg H20. Which explanation is the best to give to the patient’s family?

- None of the above
- there is a clerical error on the computation
- there were 2 different Lab Scientists who performed on the computed & on the Osmometer
- the Osmometer is not calibrated, and test needs to be repeated
the results signifies a lower chance for patient’s recovery
