A positive test shows a bluish-white streak of precipitated proteins. The degree of turbidity depends on the amount of protein in the CSF. It can vary from faint turbidity (mild to moderate elevation in CSF proteins) to dense milky precipitate (high protein content in CSF).
Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system , and is encountered in a number of neurological diseases , such as pseudomigraine, Susac's syndrome, and encephalitis.
Similarly, raised CSF protein levels and pleocytosis are frequent but non-specific. It was originally thought [5] that raised CSF protein without pleocytosis ('albuminocytological dissociation') was a characteristic feature, as it is in Guillain–Barré syndrome, but this has not been supported in more recent work.

Cerebrospinal fluid is produced by the choroid plexus in the ventricles of the brain and contained by the dura and arachnoid layers of the meninges. [23] [42] [64] The brain floats in CSF, which also transports nutrients to the brain and spinal cord. As holes form in the spinal dura mater, CSF leaks out into the surrounding space.
A clinical test formerly used for evaluation of spinal stenosis is Queckenstedt's maneuver. Nowadays, a magnetic resonance imaging is used for identification of CSF flow obstruction. It often shows the prolongation of T1 and T2 signal in CSF caudal to a level of block. [ 2 ]
lack of initial CSF pleocytosis (i.e. low CSF white blood cell count); elevated C-reactive protein; failure to sterilize the CSF before immune recovery. IRIS may be the cause of paradoxically worse outcomes for cryptococcal meningitis in immunocompetent compared with immunocompromised hosts, in whom Cryptococcus neoformans is the usual pathogen ...
Many foods marketed as 'high-protein' may not be as healthy ... When comparing foods with protein claims to those without, only 77.7% of the non-protein claim products received a “less healthy ...
CSF albumin is a measurement used to determine the levels of albumin in cerebrospinal fluid. [1] A closely related test, CSF total protein is a measurement used to determine the levels of protein in cerebrospinal fluid. [2] [3] It combines the albumin, IgG, and other proteins. It can be useful in distinguishing among causes of Meningitis.
