CSF glucose

CSF Glucose

The CSF Glucose or Cerebrospinal Fluid Glucose is a crucial test that measures the level of glucose in the cerebrospinal fluid (CSF). CSF is a clear fluid that circulates in the space surrounding the spinal cord and brain. CSF protects the brain and spinal cord from injury by acting as a cushion. Glucose is a type of sugar that the body uses for energy, and it's present in most types of body fluids.

Overview

The CSF Glucose test is often used to diagnose a variety of conditions that affect the central nervous system, particularly when other, less invasive tests are inconclusive. It can help diagnose conditions such as meningitis, encephalitis, and cancer of the brain or spinal cord.

Procedure

The CSF Glucose test is performed using a procedure called a lumbar puncture, or spinal tap. During a lumbar puncture, a needle is inserted into the lower back to collect a sample of CSF. The glucose level in the CSF is then measured and compared to the glucose level in the blood.

Interpretation of Results

A low level of glucose in the CSF may indicate the presence of a bacterial or fungal infection, tuberculosis, or meningitis. A high level of glucose in the CSF can be a sign of high blood sugar (hyperglycemia).

Risks and Complications

While the CSF Glucose test is generally safe, it does carry some risks. These include headache, infection, bleeding, and nerve damage. However, these complications are rare.
