Mumps caused by a virus from the Paramyxoviridae family, transmitted through air droplets or through direct contact with an infected person. Symptoms begin very generally with fever, headache and muscle pain, succeeded by large swellings in the neck as the salivary glands become inflamed and swollen.
When infected with the virus, the immune system produces the antibody known as IgM initially, to help the body to destroy the virus.
What might a high result mean?
Detecting the presence of Mumps IgM in the bloodstream indicates an ongoing or recent infection with the Mumps virus. It does not however, indicate immunity from past infection or from vaccination.
