Question 5
How to estimate the concentration of methanol as well as other alcohols concentration level?

	Alcohols Concentration Estimation
Estimated Conc = Osmol gap X MW / 10 Osmol gap = (measured – calculated) osmolality Calculated Osmolality = 2 X Na + BUN/2.8 + Glucose / 18 + ( ethanol/ 4.6 ) MW: Ethanol = 46 Ethylene glycol = 62 Isopropanol = 60 Methanol = 32
