Measles (Rubeola) Antibody, IgG, CSF
Also known as: MEASLGCSF
Use
The detection of antibodies to rubeola in CSF may indicate a central nervous system infection. However, it is important to consider possible contamination by blood or transfer of serum antibodies across the blood-brain barrier. This test measures the IgG antibody to measles (rubeola) in cerebrospinal fluid (CSF) and can help assess current or past exposure or immunization to the measles virus.
Special Instructions
Not a recommended test. False-positive results will occur due to the low incidence of measles in the U.S. It's important to interpret the results carefully considering the potential for contamination or blood-brain barrier transfer.
Limitations
This test has not been cleared or approved by the FDA. The presence of the IgG antibody in CSF may not definitively indicate a current infection due to possible contamination or transfer from blood. Results must be interpreted with consideration to clinical information and other diagnostic findings.
