Cerebrospinal fluid (CSF) analysis is a group of laboratory tests that measure proteins, sugar (glucose), and other chemicals in the fluid that surrounds and protects the brain and spinal cord.
Alternative NamesCerebrospinal fluid analysis
How the test is performedA sample of CSF is needed. A lumbar puncture, also called a spinal tap, is the most common way to collect this sample. For information on this procedure, see lumbar puncture. Other methods for collecting CSF are rarely used, but may be recommended in some cases. See also:
- Cisternal puncture
- Removal of CSF from a tube that is already in the CSF, such as a shunt or ventricular drain
- Ventricular puncture
After the sample is taken, it is sent to the laboratory for evaluation.
How to prepare for the testSee: Lumbar puncture
How the test will feelSee: Lumbar puncture
Why the test is performedAnalysis of CSF can help detect certain conditions and diseases. All of the following can be, but are not always, measured in a sample of CSF:
- Antibodies and DNA of common viruses
- Bacteria (including that which causes syphilis; see:VDRL test)
- Cell count
- Chloride
- Cryptococcalantigen
- Glucose
- Glutamine
- Lactate dehydrogenase
- Oligoclonal banding to look for specific proteins
- Total protein
- Whether there are cancerous cells present
- Antibodies and DNA of common viruses: None
- Bacteria: No bacteria grows in a lab culture
- Cancerous cells: No cancerous cells present
- Cell count: less than 5 white blood cells (all mononuclear) and 0 red blood cells
- Chloride: 110 to 125 mEq/L
- Fungus: None
- Glucose: 50 to 80 mg/100 mL (or greater than two-thirds of blood sugar level)
- Glutamine: 6 to 15 mg/dL
- Lactate dehydrogenase: less than 2.0 to 7.2 U/mL
- Oligoclonal bands: 0 or 1 bands that are not present in a matched serum sample
- Protein: 15 to 60 mg/100 dL
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanAn abnormal CSF analysis result may be due to many different causes, including:
- Cancer
- Encephalitis(such as West Nile and Eastern Equine)
- Hepatic encephalopathy
- Infection
- Inflammation
- Reye syndrome
- Meningitis due to bacteria, fungus, tuberculosis, or a virus

What is the correct name for the compound CsF?
The correct name for the compound CsF is cesium fluoride.
Why CsF is more soluble in water than CsI?
Solubility of an ionic compound in water depends on the extent of dissossiation of ions. CsF is more ionic than CsI due to greater electronegativity of F.The more ionic a compound, the more is the extent of dissossiation of ions, so CsF is more soluble in water than CsI
What is the bond length for LiF KF CsF?
The approximate bond lengths for LiF, KF, and CsF are as follows: LiF: around 1.55 Å (angstroms) KF: around 1.33 Å CsF: around 1.51 Å Please note that bond lengths can vary slightly depending on the specific conditions and methods used for measurement.
What is the name of the ionic compound CsF?
Cesium fluoride
Is the compound CsF ionic or molecular?
The compound CsF, which is the combination of cesium (Cs) and fluorine (F), is ionic. Cesium is a metal, so it typically forms ionic compounds with nonmetals like fluorine. In CsF, cesium donates its electron to fluorine, forming Cs+ and F- ions which are held together by electrostatic forces in an ionic bond.

How can you store CSF before analysis?
With help of God everything will be alright
What is a cerebrospinal fluid analysis used for?
The purpose of a CSF analysis is to diagnose medical disorders that affect the central nervous system.
Why RPR test not perform by csf?
The RPR (Rapid Plasma Reagin) test is a non-treponemal test used to screen for syphilis, primarily using serum rather than cerebrospinal fluid (CSF). This is because RPR detects antibodies that are typically present in the bloodstream, as they are produced in response to the infection. While CSF analysis can be useful in diagnosing neurosyphilis, RPR is not performed on CSF due to its higher sensitivity and specificity when using serum, and the complexity involved in CSF collection and analysis.
What is the removal of CSF?
In a lumbar puncture (LP) procedure, cerebrospinal fluid (CSF) is removed for analysis of protein, glucose, bacteria, etc., to assist in neurologic disease diagnosis.
Does a normal cerebrospinal fluid analysis signifies encephalitis free?
A normal cerebrospinal fluid (CSF) analysis does not definitively rule out encephalitis. While abnormal findings, such as elevated white blood cell counts, increased protein levels, or the presence of specific antibodies, can indicate encephalitis, a normal CSF analysis may occur in some cases, particularly in the early stages of the disease or in certain viral infections. Therefore, clinical symptoms and imaging studies should also be considered in conjunction with CSF analysis for an accurate diagnosis.
What is a cerebrospinal fluid?
Cerebrospinal fluid (CSF) analysis is a laboratory test to examine a sample of the fluid surrounding the brain and spinal cord.
How is cryptococcosis diagnosed?
Cryptococcosis is diagnosed through a combination of tests such as cerebrospinal fluid (CSF) analysis, blood tests, imaging studies (such as CT scans or MRIs), and cryptococcal antigen testing. CSF analysis is often crucial for diagnosing central nervous system involvement. Treatment may involve antifungal medications such as amphotericin B and fluconazole.
What is in CSF?
CsF is the chemical formula of caesium fluoride.
What is csf in medical terms?
CSF stands for cerebrospinal fluid, a clear, colorless fluid that surrounds the brain and spinal cord. It serves several important functions, including cushioning the brain, maintaining intracranial pressure, and providing vital nutrients while removing waste. CSF is produced by the choroid plexus in the brain's ventricles and circulates through the central nervous system. Its analysis can be crucial for diagnosing various neurological conditions.
Is it true that cerebrospinal fluid analysis is performed to aid in diagnoses of neurological conditions?
Yes, cerebrospinal fluid (CSF) analysis is a crucial diagnostic tool for various neurological conditions. It involves the collection and examination of the fluid surrounding the brain and spinal cord, helping to identify infections, bleeding, inflammation, and other disorders such as multiple sclerosis or meningitis. Abnormalities in CSF composition can provide valuable insights into the underlying neurological issues.
When was Colnago-CSF Bardiani created?
Colnago-CSF Bardiani was created in 1982.
