Rubeola Antibodies Blood Test, IgG

What is the purpose of this test?

Order this Rubeola (Measles) Antibodies Blood Test, IgG, which measures and detects antibodies to measles to help confirm immunity. Measles (rubeola) is a viral infection of the cells in the lungs and the back of the throat that is easily spread through coughing and sneezing or touching a surface contaminated with the virus and then touching your mouth, nose, or eyes. According to the Centers for Disease Control and Prevention (CDC), the measles virus can live for up to two hours in the air when an infected person coughs or sneezes. As a result, infected individuals are contagious for a few days before the symptoms appear. Symptoms associated with measles include fever, cough, red eyes, sensitivity to light, runny nose, sore throat, white spots inside of the mouth, and skin rashes. Most individuals recover within a couple of weeks, but about 20% develop complications, including ear infection, bronchitis, pneumonia, diarrhea, or, more rarely, encephalitis or blindness.

When should I order a Rubeola Antibodies Blood Test, IgG?

Individuals interested in determining their immunity to measles may order this test. Individuals should also note that this test cannot distinguish between a past or current infection; therefore, a positive result may indicate active infection and not immunity. However, suppose an active infection is not suspected based on the individual’s history, clinical signs, and other laboratory results. In that case, a positive IgG result is likely due to past infection, and the individual is assumed to be immune to the disease. Individuals are advised to follow up with their doctor or healthcare provider if they have significant concerns or questions about their results.
