I was a junior medical student assigned to Bellevue's pediatric tuberculosis service in the mid-1940s, one of the largest of its kind in the country. In an era when tuberculous meningitis was a common CNS infection, classic teaching held that a low CSF chloride value was almost pathognomonic of this severe disease.

We were told that CSF glucose and protein determinations were helpful in assessing the course of tuberculous meningitis but that CSF chloride determination was worthless.4,5
