Mumps Virus Antibody IgM, CSF
Use
The detection of antibodies to mumps in CSF may indicate central nervous system infection. However, consideration must be given to possible contamination by blood or transfer of serum antibodies across the blood-brain barrier. This test measures the presence of IgM antibodies specific to the mumps virus in CSF, which may indicate a current or recent infection. Persisting low levels of IgM antibodies may occur post-infection or after immunization.
Special Instructions
Not provided.
Limitations
The test results may be affected by contamination of CSF with blood or transfer of serum antibodies across the blood-brain barrier, which can lead to false positives. Low levels of IgM antibodies may persist for more than 12 months following infection or immunization, which can affect the interpretation of results.
