🧪 What is the Mumps Virus IgG Antibody Test?
The Mumps IgG antibody test detects IgG antibodies specific to the mumps virus in the blood.
These antibodies typically develop after infection or vaccination and provide long-term immunity.
This test is commonly used to:
- Check immunity status
- Confirm past infection
- Support vaccine efficacy assessment
❓ Why is the Test Done?
To:
- Determine immunity to mumps (e.g. before pregnancy, school, or healthcare employment)
- Assess response to MMR vaccine (Measles-Mumps-Rubella)
- Help diagnose recent or past mumps infection (with IgM)
- Conduct outbreak investigations or epidemiological studies
📊 Normal Range & Interpretation
Result | Interpretation |
|---|---|
Positive | IgG antibodies present – immune |
Negative | No IgG antibodies – non-immune or very early exposure |
Equivocal | Borderline result – retesting advised |
Most individuals who are vaccinated or recovered from mumps have detectable IgG.
📈 Interpretation of Results
Result | Meaning |
|---|---|
Positive IgG | Past infection or successful vaccination → Immune |
Negative IgG | No prior infection or immunization → At risk |
IgM also positive | Suggests recent or current mumps infection |
🧠 Associated Organs & Conditions
System/Organ | Possible Mumps-Related Complications |
|---|---|
Salivary Glands | Parotitis (swelling of parotid glands) |
CNS | Meningitis, encephalitis |
Reproductive Organs | Orchitis (testicular swelling), oophoritis, infertility |
Pancreas | Pancreatitis |
Ears | Sensorineural deafness (rare) |

- MMR IgG panel – combined measles, mumps, rubella immunity check
- PCR for mumps virus – if active infection is suspected
- Salivary gland ultrasound – for parotitis assessment
