A cerebrospinal fluid (CSF) culture is a laboratory test to look for bacteria, fungi, and viruses in the clear fluid that moves in the space surrounding the spinal cord.
Alternative NamesCulture - CSF; Spinal fluid culture; CSF culture
How the test is performedA sample of CSF 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 the laboratory, where it is placed in a special dish (called a culture medium). The laboratory personnel watch to see if bacteria, fungi, or viruses grow in the dish. Growth means there is an infection.
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 feelFor information on how it will feel to have a sample of CSF fluid removed, see spinal tap.
Why the test is performedYour doctor may order this test if you have signs of an infection that affects your brain or nervous system. The test will help identify the origin of the infection. This helps your doctor determine the best course of treatment.
Normal ValuesA normal result means no bacteria, viruses, or fungi grew in the laboratory dish. This is called a negative result.
What abnormal results meanAn abnormal result means a fungus, virus, or bacterium grew in the laboratory dish. This is considered a positive culture and is a sign of an infectious meningitis. This does not necessarily mean the infection is contagious, unless it is meningococcal meningitis.

Cerebrospinal fluid leak ICD-9 code?
If the cerebrospinal fluid is leaking from the nose/mouth it is called Cerebrospinal fluid rhinorrhea and that code is 349.81. If the fluid is leaking from the ears, it is called Cerebrospinal fluid otorrhea and that code is 388.61. Brenda M. St. Louis, MO
Does the central canal contain cerebrospinal fluid?
yes the canal does contain cerebrospinal fluid....
IS the cerebrospinal fluid secreted by arachnoid villi?
No, cerebrospinal fluid is produced by the choroid plexus in the brain's ventricles. Arachnoid villi function to reabsorb and return cerebrospinal fluid back into the bloodstream.
Do the skull meninges and cerebrospinal fluid protect the brain?
The skull, meninges, and cerebrospinal fluid protect the brain.
Where will the cerebrospinal fluid in the third ventricle drain into?
The cerebrospinal fluid in the third ventricle will drain into the fourth ventricle.
Does cerebrospinal fluid contain blood?
Ideally, cerebrospinal fluid should not contain blood. The presence of blood in cerebrospinal fluid can indicate a potential injury or bleeding within the brain or spinal cord. It is important to investigate the cause of the blood in the cerebrospinal fluid to determine the appropriate treatment.

Is cerebrospinal fluid found in the frontal sinus?
Cerebrospinal fluid is not found in the frontal sinus. The frontal sinus is an air-filled cavity within the frontal bone of the skull, while cerebrospinal fluid is a clear fluid that surrounds the brain and spinal cord within the subarachnoid space.
What is the normal pH of cerebrospinal fluid and bile?
The normal pH of cerebrospinal fluid is around 7.33-7.41. Bile typically has a slightly alkaline pH ranging from 7.6 to 8.6.
