Aivoselkäydinnestenäyte

Aivoselkäydinnestenäyte, also known as cerebrospinal fluid (CSF) sample, refers to the fluid that surrounds the brain and spinal cord. It is a clear, colorless fluid that acts as a cushion, protecting the central nervous system from injury. A sample of this fluid can be collected for diagnostic purposes.

The collection of a CSF sample is typically performed through a lumbar puncture, commonly called a spinal tap. This procedure involves inserting a needle into the lower back, between two vertebrae, to access the subarachnoid space where the CSF circulates. The process is usually done under local anesthesia.

Analyzing a CSF sample can provide valuable information for diagnosing a wide range of neurological conditions. These include infections such as meningitis and encephalitis, inflammatory diseases like multiple sclerosis, and certain types of cancer that may have spread to the central nervous system. It can also help detect bleeding within the brain or spinal cord.

The analysis of the CSF sample involves examining its physical characteristics, such as clarity and color, and performing laboratory tests. These tests may include cell counts, protein and glucose levels, and cultures to identify microorganisms. Specific antibody tests or the presence of abnormal cells can also be detected. The results of these analyses are crucial for guiding treatment decisions and monitoring the progression of neurological disorders.
