Measles (Rubeola) Antibodies, IgG and IgM
Also known as: MEASLE PAN
Use
The test aids in the diagnosis of measles infection. It is used to detect antibodies IgG and IgM which indicate whether there is a current or past exposure to measles or an immunization history. IgM presence suggests a recent primary infection, while IgG can indicate past exposure or immunization.
Special Instructions
Not provided.
Limitations
False-negative IgM results are possible if the specimen was collected too soon after exposure. Molecular testing may be helpful in such cases. False-positive IgM results are also possible. The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
