R83.4: Abnormal findings in cerebrospinal fluid : abnormal immunological findings

There are cavities with cerebrospinal fluid in the brain, around the brain and around the spinal cord. Among other things, the cerebrospinal fluid cushions the brain and spinal cord during knocks and also nourishes the brain cells. The cerebrospinal fluid is usually taken from the lower back for examination. The cerebrospinal fluid normally only contains a certain amount of different substances. These substances include certain cells and certain proteins, for example.

The immune system protects the body from pathogens and foreign substances. The immune system can also destroy cells in the body that have pathologically changed. The body’s immune system is made up of different types of immune cells. Some immune cells can destroy pathogens or foreign bodies themselves. Other immune cells produce certain antibodies. In your cerebrospinal fluid, the amount of immune cells or certain proteins of the immune system had changed.

If the amount of substances in the cerebrospinal fluid has changed, this can sometimes be an indication of disease. The results can also depend on when the cerebrospinal fluid is sampled or how the cerebrospinal fluid is stored until it is examined, for example.
