selkäydinnestenäytteen

A selkäydinnesteenäyte, often referred to as a cerebrospinal fluid (CSF) sample in English, is a medical test involving the collection of fluid that surrounds the brain and spinal cord. This procedure is commonly known as a lumbar puncture or spinal tap. It is performed by inserting a needle into the lower part of the spine, typically between the vertebrae in the lumbar region, to withdraw a small amount of CSF.

The collected CSF sample is then sent to a laboratory for analysis. This analysis can reveal a variety of important information about the patient's neurological health. It is frequently used to diagnose infections of the central nervous system, such as meningitis and encephalitis. The presence of bacteria, viruses, or other pathogens, as well as elevated white blood cell counts, can indicate an infection.

Furthermore, CSF analysis can aid in the diagnosis of inflammatory and autoimmune conditions affecting the brain and spinal cord, like multiple sclerosis. It can also help detect certain types of cancer that have spread to the central nervous system and diagnose conditions such as Guillain-Barré syndrome. In some cases, CSF pressure can also be measured during the procedure, which is relevant for diagnosing conditions like hydrocephalus or idiopathic intracranial hypertension. The results of the CSF analysis, combined with clinical symptoms and other diagnostic tests, guide medical professionals in determining the most appropriate treatment plan for the patient.
