A cerebrospinal fluid (CSF) smear is a microscopic examination of the clear fluid that moves in the space surrounding the spinal cord and brain. CSF protects the brain and spinal cord from injury.
Alternative NamesSpinal fluid smear; Cerebrospinal fluid smear
How the test is performedA sample of CSF fluid is needed. This is usually done with a lumbar puncture. For information on how this procedure is performed, see spinal tap.
The sample is sent to a laboratory, where a tiny amount is spread on a glass slide. A member of the laboratory team looks at the sample under a microscope. The smear shows the color of the fluid and the number and shape of cells present in the fluid. Other tests, such as a Gram stain, may be done to check for bacteria.
How to prepare for the testFor information on how to prepare for the procedure to obtain the CSF sample, see spinal tap.
How the test will feelThe laboratory test is painless and does not involve the patient.
For information on how it will feel to have a sample of CSF fluid removed, see spinal tap.
Why the test is performedThe test is done to check for signs of infection in a sample of CSF.
Normal ValuesNormal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanIf bacteria are present, that indicates bacterial meningitis. Other kinds of infections might include tuberculosis and fungal infections. Certain bacteria or viruses can also be detected using special tests.
What the risks areA laboratory smear poses no risk to the patient. For risks associated with the procedure done to get a CSF sample, see spinal tap.

Is glucose found in CSF fluid?
Yes. Glucose is found there in CSF fluid. CSF glucose level is commonly done by your doctor.
What is the normal flora of CSF?
there ara no microbial normal flora in the csf
What contains CSF?
The spine and brain contain Cerebrospinal fluid (CSF)
How and where is the CSF formed?
Most of the CSF is formed by the choroid plexuses in the ventricles of the brain. Some is also produced by ependymal cells.
Where does the csf drain from subarachnoid space?
In the brain we have small protrusions of the arachnoid and subarachnoid space into the venous system. These protrusions are called arachnoid villi or arachnoid granulations and they allow for drainage of CSF into the venous system. Another source of CSF drainage is the lymphatic system.
What is in CSF?
CsF is the chemical formula of caesium fluoride.
Is glucose found in CSF fluid?
Yes. Glucose is found there in CSF fluid. CSF glucose level is commonly done by your doctor.

When was Colnago-CSF Bardiani created?
Colnago-CSF Bardiani was created in 1982.
Why is csf protein in newborn is high normally?
Since blood-csf barrier is not well developed in neonates protein leak from blood to csf occurs...so csf protein is high in neonates and infants...for similar reason csf protein is elevated in all meningitis due to vascular permeability...
What is CsF in chemistry?
CsF is the chemical formula of caesium fluoride.
How much cerebrospinal fluid does brain contain?
CSF volume is 150mls and the daily production of CSF is 550mls/day. Effectively meaning that CSF changes 3-4 times a day
What is the name for CsF?
The formula name for the element CsF is Caesium fluoride.
What do ventricles contain?
csf
What do the ventricles contain?
csf
Where does CSF circulate and where is it returned to the blood?
CSF is cerebrospinal fluid . It is a colorless fluid found in the brain and spine. It is formed in the lateral ventricles from where it circulates through the interventricular foramens into the third ventricle and finally into the fourth ventricle.
