Description
The MMR IgG panel measures immunoglobulin G (IgG) antibodies in your blood against measles, mumps, and rubella viruses. This test determines whether a person has immunity to these infections, either from previous vaccination or past infection.
Purpose of the Test
- Assess immunity: Confirms if you are protected against measles, mumps, and rubella.
- Pre-vaccination screening: Determines if a booster dose of the MMR vaccine is needed.
- Post-exposure assessment: Helps identify whether an individual is at risk after contact with someone who has MMR.
- Prenatal screening: Ensures immunity in women before or during pregnancy to prevent congenital rubella syndrome.
Clinical Significance
- Measles: Highly contagious viral infection causing fever, cough, runny nose, rash, and in severe cases, pneumonia or encephalitis.
- Mumps: Viral infection causing fever, headache, and painful swelling of the salivary glands; can lead to complications like orchitis or meningitis.
- Rubella: Mild viral infection in children and adults, but can cause severe birth defects if a pregnant woman is infected.
Test Details
- Sample: Blood
- Preparation: Fasting not required
- Interpretation:
- Positive IgG: Indicates immunity to the virus.
- Negative IgG: Suggests susceptibility, and vaccination may be recommended.
This panel is commonly ordered for school entry, healthcare workers, travelers, or women planning pregnancy to ensure protection against these preventable viral infections.
