Typically for an OCB analysis, the CSF is concentrated and the serum is diluted. After this dilution/concentration prealbumin appears as higher on CSF. Albumin is typically the dominant band on both fluids. Transferrin is another prominent protein on CSF column because its small molecular size easily increases its filtration in to CSF.
In patients with pseudomigraines, studies have shown concentrations ranging from 10 to 760 cells per mm 3, with a mean concentration of 199 ± 174 cells per mm 3. [3] Increases in white blood cell count to more than 500 cells per mm 3 can cause the CSF to appear cloudy when observed during diagnostic tests.

Several conditions can mimic MS. Given the unknown pathogenesis of MS, its differential diagnosis is based in exclusion of known conditions. [citation needed] Very close diseases with similar symptoms are the whole "inflammatory demyelinating diseases spectrum", specially neuromyelitis optica and anti-MOG associated encephalomyelitis. [citation ...
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 ...
Diagnosis of MS has always been made by clinical examination, supported by MRI or CSF tests. According with both the pure autoimmune hypothesis and the immune-mediated hypothesis, [ 5 ] researchers expect to find biomarkers able to yield a better diagnosis, and able to predict the response to the different available treatments.
The rate of CSF formation in humans is about 0.3–0.4 ml per minute and the total CSF volume is 90–150 ml in adults. [ 2 ] Traditionally, CSF was evaluated mainly using invasive procedures such as lumbar puncture, myelographies, radioisotope studies, and intracranial pressure monitoring.
Diagnosis is most commonly made by lumbar puncture to detect malignant cells in the CSF, although the tests may be negative in roughly 10% of patients. [5] Diagnosis often requires a high index of suspicion and is confirmed by neuroimaging and cerebrospinal fluid analysis. [21] CSF examination is the most useful diagnostic tool for NM.
