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.
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.
CSF is derived from blood plasma and is largely similar to it, except that CSF is nearly protein-free compared with plasma and has some different electrolyte levels. Due to the way it is produced, CSF has a lower chloride level than plasma, and a higher sodium level. [2] [6] CSF contains approximately 0.59% plasma proteins, or approximately 15 ...
CSF/serum albumin ratio is a test performed to compare the levels of albumin in the cerebrospinal fluid and the serum. It is useful as a measure of the integrity of the blood–brain barrier . [ 1 ] [ 2 ] [ 3 ]
Under normal conditions, there are usually less than 5 white blood cells per μL of CSF. In a pleocytic setting, the number of lymphocytes can jump to more than 1,000 cells per μL. Increases in lymphocyte count are often accompanied by an increase in cerebrospinal protein concentrations in addition to pleocytosis of other types of white blood ...
In normal infants, AFP in CSF is: [18] median 61 kIU/L (5th-95th centile: 2-889 kIU/L) in infants -69 to 31 days old; median 1.2 kIU/L (5th-95th centile: 0.1-12.5 kIU/L) in infants 32 to 110 days old; Levels of AFP in CSF decline with gestational age in proportion to levels of AFP in serum [19]
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 ( mmHg ) and at rest, is normally 7–15 mmHg for a supine adult.
