How is serum osmolality measured
WebThe Calculated Serum Osmolality formula is defined as the number of moles of dissolved particles (charged or uncharged solutes) per kilogram of serum and is represented as Oserum = (2*[Na]serum)+ (Gserum/18)+ (BUN/2.8) or Calculated Serum Osmolality = (2*Serum Sodium)+ (Serum Glucose/18)+ (Blood Urea Nitrogen/2.8). WebSerum Osmolar Gap (top of page) The osmolar gap is determined by subtracting the calculated osmolality from the measured osmolality. While there are many formulae …
