What does CSF mean in medical terms?
Cerebrospinal fluid (CSF, shown in blue) is made by tissue that lines the ventricles (hollow spaces) in the brain. It flows in and around the brain and spinal cord to help cushion them from injury and provide nutrients.
What is CSF microscopy?
CSF cytology – a cytocentrifuged sample is treated with a special stain and examined under a microscope for abnormal cells. This is often done when a CNS tumour or metastatic cancer is suspected.
What is Xanthochromic mean?
Xanthochromia is the presence of bilirubin in the CSF. This finding can be the only positive marker that a patient is suffering from an acute SAH. It is an important finding in distinguishing between traumatic tap and a SAH. Visual inspection of the CSF is the most common method of detection.
What is CSF pathology?
Cerebrospinal fluid (CSF) is a clear watery liquid filtrate that is formed by the choroid plexus, special tissue that has many blood vessels and lines the small spaces or chambers (ventricles) in the brain. CSF flows around the brain and spinal cord, surrounding and protecting them.
How do you read CSF results?
Interpretation of CSF results from lumbar puncture (LP)
- Appearance: Clear.
- Opening pressure: 10-20 cmCSF.
- WBC count: 0-5 cells/µL. < 2 polymorphonucleocytes [PMN])
- Glucose level: >60% of serum glucose.
- Protein level: < 45 mg/dL.
- Consider additional tests: CSF culture, others depending on clinical findings.
What is a microscopic examination?
Microscopic examination, which identifies and counts the type of cells, casts, crystals, and other components such as bacteria and mucus that can be present in urine.
What does bilirubin in CSF mean?
Xanthochromia is the term used for cerebrospinal fluid (CSF) stained yellow with bilirubin. This is the result of a recent subarachnoid or cerebral bleed, head injury, or previous bloody tap. Bilirubin is formed ONLY in vivo, and not after CSF has been taken.
What is CSF supernatant?
Supernatant Color Xanthochromia is a yellow, orange, or pink discoloration of the CSF, most often caused by the lysis of RBCs resulting in hemoglobin breakdown to oxyhemoglobin, methemoglobin, and bilirubin.
Why is spinal fluid test done?
This test is done to measure pressures within the CSF and to collect a sample of the fluid for further testing. CSF analysis can be used to diagnose certain neurologic disorders. These may include infections (such as meningitis) and brain or spinal cord damage.
Why CSF test is done?
Why the Test is Performed This test is done to measure pressures within the CSF and to collect a sample of the fluid for further testing. CSF analysis can be used to diagnose certain neurologic disorders. These may include infections (such as meningitis) and brain or spinal cord damage.
What do they look for in a CSF test?
The tests may look for proteins, sugar (glucose), and other substances. A sample of CSF is needed. A lumbar puncture, also called a spinal tap, is the most common way to collect this sample. Less common ways to take a fluid sample include:
What is a cerebrospinal fluid (CSF) analysis?
What is a cerebrospinal fluid (CSF) analysis? Cerebrospinal fluid (CSF) is a clear, colorless liquid found in your brain and spinal cord. The brain and spinal cord make up your central nervous system.
What is the function of the CSF?
Nutrition – The CSF contains glucose, proteins, lipids, and electrolytes, providing essential CNS nutrition. 5. Immune function – The CSF contains immunoglobulins and mononuclear cells. The 5 minute video below is a great summary of the CSF
What is a normal CSF level?
Analysis 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: Normal results include: Glucose: 50 to 80 mg/dL or 2.77 to 4.44 mmol/L (or greater than two-thirds of blood sugar level)
