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.
type 3, oligoclonal bands in CSF and serum with additional bands in CSF; type 4, identical oligoclonal bands in CSF and serum, type 5, monoclonal bands in CSF and serum, type 6, presence of a single band limited to the CSF. Type 2 and 3 indicate intrathecal synthesis, and the rest are considered as negative results (No MS).
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 ...
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 ...
Pandy's test (or Pandy's reaction) is done on the CSF (cerebrospinal fluid) to detect the elevated levels of proteins (mainly globulins). This test is named after the Hungarian neurologist , Pándy Kálmán (1868–1945) who developed this test in the year 1910.
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 ...
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]
