Input interpretation
serum osmolarity
Equation
S_osm = 2 (S_Na + S_K) + BUN/2.8 + GLU/18 | S_osm | serum osmolarity BUN | blood urea nitrogen GLU | serum glucose S_K | serum potassium S_Na | serum sodium
Input values
blood urea nitrogen | 10 mg/dL (milligrams per deciliter) serum glucose | 90 mg/dL (milligrams per deciliter) serum potassium | 4 mmol/L (millimoles per liter) serum sodium | 140 mmol/L (millimoles per liter)
Result
serum osmolarity | 297 mOsm/L (milliosmoles per liter)
