Understanding Lab Tests for Mumps Infection
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Mumps is a contagious viral infection that primarily affects the salivary glands, causing painful swelling on one or both sides of the face. While mumps can often be diagnosed based on clinical symptoms, blood testing plays a crucial role in confirming the diagnosis and determining immunity status.
Recommended Test
Mumps Virus Antibody (IgG)
This test measures IgG antibodies against the mumps virus in the blood. Elevated levels indicate a past infection with mumps, as the immune system produces these antibodies in response to the viral infection. This test is essential for confirming previous exposure to mumps and determining long-term immunity status.

Why Blood Testing is Important for Mumps
Blood tests for mumps can help confirm a past infection, determine immunity status, and distinguish mumps from other conditions that cause similar symptoms. This information is particularly valuable for healthcare providers when assessing vaccination needs or investigating outbreaks.
Understanding Your Results
The presence of mumps IgG antibodies typically indicates either past infection or successful vaccination against mumps. Your healthcare provider will interpret your results in the context of your symptoms, vaccination history, and potential exposure to help determine the most appropriate course of action.
