WebCSF Osmolality in Ketoacidosis. To the Editor: The article by Ohman and his co-workers 1 provides interesting data on the relation between blood and cerebrospinal fluid (CSF) in … WebSerum osmolality was 283.6 ± 6.5 mOsm/kg and CSF osmolality was 289.5 ± 6.6 mOsm/kg. Because the specific gravity of serum and CSF is known to be 1.024-1.028 and 1.004-1.007, respectively, the estimated average of osmolarity (mOsm/L) in the serum and CSF covered exactly the same range (i.e., 290.5-291.5 mOsm/L).
