To calculate plasma osmolarity (osmolality) use the following equation:
Posm = 2[Na+] + [Glucose]/18 + [ BUN ]/2.8
The above equation holds true if the glucose & ureas blood chemistry units are given as: mg/dL.
If the units are given as: mmol/l; then the calculated osmolality is given by:
P.OSM = 2[NA] + 2[K+] + [Urea] + [Glucose

for two reasons:
to determine whether serum water content deviates widely from normal;
or screen for the presence of foreign low molecular-weight substances in the blood
