What is this test?

The European tick-borne encephalitis virus IgM antibody test is a laboratory test performed on cerebrospinal fluid (CSF), the clear fluid surrounding your brain and spinal cord. It detects IgM antibodies that your immune system produces in response to the tick-borne encephalitis virus (TBEV). This test uses immunoassay techniques to identify whether these specific antibodies are present, helping doctors determine if you have a current or recent infection affecting your central nervous system.

How is the sample collected?

Cerebrospinal fluid is collected through a procedure called a lumbar puncture, commonly known as a spinal tap. During this procedure, a healthcare provider inserts a thin needle between the bones (vertebrae) in your lower back to withdraw a small amount of CSF. The fluid is then sent to a laboratory for analysis. This method allows direct detection of antibodies in the fluid that surrounds the brain and spinal cord, which is particularly important for diagnosing neurological infections.

Why might I need this test?

Your doctor may order this test if you have symptoms of tick-borne encephalitis, especially if you have been in areas where TBE is common (such as parts of Central, Eastern, and Northern Europe and northern Asia). Symptoms typically include fever, headache, fatigue, muscle aches, and in more severe cases, meningitis (inflammation of the membranes surrounding the brain) or encephalitis (inflammation of the brain). The test is particularly important when symptoms suggest the infection has spread to the central nervous system.
