Chapter Information

Formulas and conversion tables used in the chapters discussing alcohols.

FormulasTop

Anion gap = Serum sodium (mEq/L) – [serum chloride (mEq/L) + serum bicarbonate (mEq/L)]

Note: mEq/L = mmol/L; an anion gap ≥12 is considered high (note normal values in your laboratory).

Osmolar gap = Measured osmolality (mOsm/L) – calculated osmolarity

Note: An osmolar gap >10 mOsm/L is considered high.

Calculated osmolarity (mOsm/L) = 2 × [sodium (mmol/L)] + [glucose (mmol/L)] + [urea (mmol/L)] + 1.25 × [ethanol (mmol/L)]
