  2. List of reference ranges for cerebrospinal fluid - Wikipedia

    en.wikipedia.org/wiki/List_of_reference_ranges...

    Reference ranges for ions and metals in CSF [1] Substance Lower limit Upper limit Unit Corresponds to % of that in plasma [clarification needed] Osmolality: 280 [1 ...

  3. CSF glucose - Wikipedia

    en.wikipedia.org/wiki/CSF_glucose

    CSF glucose levels can be useful in distinguishing among causes of meningitis as more than 50% of patients with bacterial meningitis have decreased CSF glucose levels while patients with viral meningitis usually have normal CSF glucose levels. Decrease in glucose levels during a CNS infection is caused due to glycolysis by both white cells and ...

  4. CSF/serum glucose ratio - Wikipedia

    en.wikipedia.org/wiki/CSF/serum_glucose_ratio

    The CSF/serum glucose ratio, also known as CSF/blood glucose ratio, is a measurement used to compare CSF glucose and blood sugar. Because many bacteria metabolize glucose, and because the blood–brain barrier minimizes transversal, the ratio can be useful in determining whether there is a bacterial infection in the CSF. The normal ratio is 0.6 ...

  5. Cerebrospinal fluid flow MRI - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_Fluid_Flow_MRI

    Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [1] CSF Fluid Flow MRI detects back and forth flow of Cerebrospinal fluid that corresponds to vascular pulsations from mostly the cardiac cycle of the choroid plexus. Bulk transport of CSF, characterized by CSF circulation through the Central ...

  6. CSF albumin - Wikipedia

    en.wikipedia.org/wiki/CSF_albumin

    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.

  7. Cerebrospinal fluid - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid

    Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialised ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. In humans, there is about 125 mL of CSF at any one time ...

  8. Intracranial pressure - Wikipedia

    en.wikipedia.org/wiki/Intracranial_pressure

    Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]

  9. Pandy's test - Wikipedia

    en.wikipedia.org/wiki/Pandy's_test

    Proteins in the cerebrospinal fluid, normally albumin and globulin are present in the ratio of 8 to 1. Increases in protein levels are of diagnostic value in neurological diseases. The normal CSF is clear and transparent fluid. The Pandy's reaction makes it translucent or opaque.
